@RogerS Thanks!

1. Radeon driver is 22.5.1 w/ fresh install to ensure isn't corrupted.
    
2. Shouldn't be any iGPU. My CPU is a i7-6950X I don't believe those came with integrated GPU. My Motherboard doesn't have any integrated graphics either.
    
3. I'll try a reset.

More of gripes if Magix reads this forum: Right now I'm waiting for the extremely SLOW Vegas downloader to obtain the most recent build of Vegas 20 (if there's a newer build?). I have a 50mbps internet connection and this downloader has taken over an hour and counting. My license manager on Magix.com is broken (separate issue). It's been difficult figuring out what is the most recent build of Vegas 20.

@RogerS tried reset on Vegas 19 which is experiencing the same issue (Vegas 20 is uninstalled waiting for latest installer to finish downloading).

Reset had no effect. I did get the dialog asking if I wanted to reset Vegas which I did in addition to purging cash files. I did that and went to relaunch Vegas. It's crashes on the splash screen... Giving me the Windows "Problem Report" dialog.

Reinstall unsuccessful I finished the download of Vegas 20. Reinstalling the software had no effect. It still crashes upon loading splash screen.

I really appreciate your help. I'm in quite the bind. Need to be working but am stuck here as Vegas is broken :(

Maybe issue is indeed with BCC / Borris FX. Below is a copy of the Problem Report... I didn't realize I could expand the problem to see details.

I'm trying to uninstall BCC but the installer / uninstaller is corrupted.

There is only one build of VP 20 at present (build 139) so you're on the right one.

Not sure about how to get rid of Boris if the installer is corrupted- manually move plugins out of that folder for now and see if Vegas at least launches?

Completed two more actions...

1. Reisntalled driver version 22.5.1 (stable version) again. This time I checked "Factory reset". Had no effect. I even restarted PC twice after doing this and before loading vegas.

2. Renamed plugin folder from C:\Program Files\Common Files\OFX\Plugins to  C:\Program Files\Common Files\OFX\xxxPlugins

Vegas 20 NLE will now load, however, crashes upon trying to load a project.

Does the project have a BCC plugin in use? Perhaps try a project that doesn't use them or creating a new project and see if it works?

Thanks for suggestion. I just tried it...

1. I loaded multiple different projects. One with a smaller timeline did successfully load. However, all others crashed.

2. I created a project from scratch. It worked so long as I added one clip at a time for the first 8 clips or so. Then I went to drag say 20 clips on the timeline at the same time. It crashed.

Side note, I honestly, don't use any of the 3rd party plugins despite they come with upgrades and I had them installed.

I also booted in safe mode. Vegas still crashes in same fashion. However, the error reporting dialog didn't crash so I was able to capture it:

I believe I may have isolated the issue. I took the exception "Fault Module" above and renamed it. It appears the HVEC issues have resurfaced as experienced in V19. If I load projects without HVEC (I have very few) Vegas 20 works. If I load with HVEC it does not work. File I/O is set to "Enable legacy HEVC decoding.

I isolated the problem libraries. They are in C:\Program Files\VEGAS\VEGAS Pro 20.0\FileIO Plug-Ins\mxhevcplug by renaming folder to to C:\Program Files\VEGAS\VEGAS Pro 20.0\FileIO Plug-Ins\XXXmxhevcplug Now Vegas 20 is stable. However, it will not process any HVEC / h.265 files.

I also restored the name for the plugins folder (previous post). The issue was not the plugins. It appears to be the HEVC libraries in that folder.

I'm going to attempt another reinstall and see if that folder is deleted with it's uninstalled. To try and rule out any possibility of module corruption.

@weinerschizel Hi, can you share the MediaInfo of those HEVC files,?

There's an App called MediaInfo, download it, it's free & a fast download with no added adverts or any of that rubbish. https://mediaarea.net/en/MediaInfo

After downloading, right click on the media file in your Windows folder, open MediaInfo, choose Text from the options at the top, Copy & paste the information in a new comment on here 👍

Like this -

Another resintall: I uninstalled and WHIPED the Vegas 20 program folder. It appears they do leave residual files in the program folders directory. Then I reinstalled. Issue persists.

I assume this makes use of different library (dll) files in that problem folder...

Turn off Legacy HEVC Decoder: issue is worse, software unstable upon loading. However, managed to quickly switch back to Legacy HEVC Decoder. Issue Persists.

Decoder Options: there are three options; off, auto, and another. I'm testing these three to see if any helps the issue. All three options, even off, has no effect on the issue.

Deleted .sfk files for HEVC clips in project Had no effect. Issue persists.

Restarting system to see if this persists. I've no idea if there's dependencies for the library files that are crashing? Or how deep down the rabbit hole these error reports go.

@weinerschizel Thanks, Hero 10 HEVC files come up quite often on this forum but with my novice eye that file looks ok, I may well be missing something tho,

Do you have Quicktime installed & if you want you can upload a problem file to Google Drive or Dropbox etc so we can try it out?

& i think i would do the Reinstall that Roger suggested to reset & undo all that renaming you've done, you shouldn't have to do all that,

I do have Google Drive. I'm moving it to a folder to sync... However, it is going to take a LONG time to upload the project (several days?) It's 37.5GB.

On the note of Corrupted Metadata / video files... Now that you mention that, I notice Windows hangs when I click on the folder with the Hero 10 HEVC files. It hangs for a second or so then opens it. Perhaps we're onto something? I'm going to search forum...

@weinerschizel don't need the whole project, just one of those HEVC files, just a small one will do.

I have my computer loading the whole project up to Google Drive. The GoPro files should start loading by tomorrow. They're the largest portion of the project. I'll link one up here when they start loading...

Other stability issues (crashing on load) aside, I seem to have made some progress. I went to my project archive and have now successfully loaded an older project with HEVC GoPro files in it. No clue what I did that resolved that issue as I've tried so many different things.

I took a new timeline and attempted to drag the GoPro files form the problem project onto the timeline. It crashes, error report below:

I was crashing fairly often editing GoPro 11 HEVC. No explanation for why it became significantly more stable after I did a Control-Shift startup reset. Only change to the default settings was to uncheck the Legacy HVEC option under File I/O after the reset.

It crashed on load screen when trying to restart software.

I do not know if this would help you but my Vegas Pro 20 365 would crash searching for VST plugins.

From My post:

After looking at the error report and seeing that the sfvstwrap.dll was causing these issues, I deleted it and now Vegas opens with no crashes. BUT I have no VST plugins installed within Vegas now. I do not know if this will affect the stability of Vegas with this file deleted? but so far I am having no problems. I sent this to Magix support. Thanks for all of the help and suggestions. I may be running a crippled Vegas, but I never used the VST plugins anyway.

And a response from Magix:

This appears to be a known issue specifically with VST Wrapper and VP20. We are currently developing a fix for it but it will likely not be released until the next update.

The VST engine in 20 seems immature so I'm doing audio edits in VP 19 now until it's improved. Perhaps delete some of the VST folders that 20 can see until it opens right.

THanks @Sassylola & @Hamilton53. I will try both your suggestions. Seems like I already tried to uncheck Legacy HEVC decoding but will try it again.

Haven't tried removing the sfvtwrap.dll will try that.

For last hour I've tried:

Tried all combinations of first two internal HEVC settings on list (hold shift, click options). It either reports all HEVC files offline or crashes. No help there.

Tried moving files in and out of the project. I can find no one specific HEVC file that's causing the issue. Leads me to believe the issue isn't with encoding on files.

Side note Vegas is unstable on startup. If it crashed on previous close it'll likely crash on the next startup during the loading screen. Quite annoying.

If any Vegas developers are reading this. YOU NEED TO DO EXCEPTION HANDLING IN YOUR SOFTWARE. YOU CAN CAPTURE THESE EXCEPTIONS AND GRACEFULLY HANDLE THEM!!

I got the project to work. However, am unable to isolate exactly what caused the issue. And unsure why it was fickle with some projects including HEVC files while not others.

Last couple things I did... I have three audio chipsets, there's a conflict somewhere in there.

Audio Device 1: I have the RealTech whatever on my motherboard (I NEVER use this, should see if I can disable in BIOS).

Audio Device 2: I have a condenser microphone for doing narrative work. It run through a Rode AL-1 USB setup. This provides audio in and audio out.

Audio Device 3: the one run through my Radeon 480x / GPU. This is my main audio and goes to speakers on display.

I noticed if I had the Rode setup plugged in I could no longer use my GPU as an audio output. It flat out wasn't in the sound settings as if it wasn't even in my PC. When I unplugged the Rode USB setup I could use my display. It seems I had the Rode box unplugged and issue persisted so maybe this isn't it?? However, this time I made sure I reset the PC before trying it w/o the Rode box.

@Hamilton53, I was able to uncheck Legacy HEVC decoding and the project works! I have no clue but out of the blue w/o any updates Vegas 20 seems to have fixed itself??? I don't know if was this and the Rode conflict... or what fixed it. Not even sure why this project wouldn't work but others would.

Just luck? I don't have a specific item that fixed the issue (for now?). I'm fried been troubleshooting this for 8 hours straight. Ready to call it a day.

Thanks to everyone who helped!!! Really appreciate all the great ideas to keep me trying.

I have my computer loading the whole project up to Google Drive. The GoPro files should start loading by tomorrow. They're the largest portion of the project. I'll link one up here when they start loading...

 

@weinerschizel  Like I said I only wanted 1 small HEVC file, I hope you get it working.
