"I'm using the latest graphics driver" doesn't mean what it used to... there are multiple types of graphics drivers now, some are for gaming use, others for studio use. Use the driver update utility in the VEGAS help menu to ensure you have the ones installed that it wants you to.

One thing could be to try to re-encode the drone and GoPro files in case that's the cause of the issues in Vegas. I'm guessing MXVideoAllocator means you are working with HEVC files?

You don't say what the CPU is but if you have the NVIDIA card doing decoding of HEVC (see preferences file i/o) that could be related to the crashes (I find my Intel QSV decoder the more stable of the two in Vegas).

These days I re-encode all zoom and phone footage and it helps. Shutter Encoder or Handbrake can handle the task and are both free!

Like I said in my original post I'm using the studio driver "NVIDIA GeForce RTX 3080 - Studio driver 516.59 (latest version 06/29/2022)". That is the version that Vegas utility recommends.

I'm using ​Intel i9-12900K 8P/16 + 8E 3.20GHz so decoding should be on the iGPU. I wasn't having any issues at all in 550 with same footage.

Can you double check in preferences, file io?

Still happening Vegas 20 Build 136. For now I continue to use Vegas 19 Build 550 without issue. I've sent another support request with all my info.

Did basic Color Grade in Color Panel (Alt + G). Even used Shutter Encoder to Transcode to ProRes 422 and threw on timeline as well. No crash.

Rendered the two clips, total time of 7 min 34 secs 18 frames in just over 9 minutes using the MAGIX HEVC (VCE) UHD 2160p 59.940 with default settings.

Computer specs in signature.

Me, I likey VP 20!

PS I'm still on VP19

Yep that's the version I'm running. I pretty much keep them up to date unless I'm in the middle of a project.
 

We have received the dump files from this crash (thank you, baksideDisaster_Flicks), and we are analyzing them with hopes of having a fix in the near future.

This is great news! Thanks for the update.

Hello, you mean you will update VP19 too if you find the problem ? Cause i have sent some crashlogs too (they might contain angry words inside).

I'm having the exact same problem in Vegas 19 643 and Vegas 20! Any updates?

Same here. I had a crash/file corruption in VP20. Screens blinked off an on - you name it. Now, similar things happen in VP19 (643) as well. I hadn't had an issue with 19 at all (it was FAR more stable than 18 for me) until the monitor/driver blitz - now it happens in 19 too. One of the error messages I've seen (couldn't take a screen cuz the whole system was frozen) said something about a floating point error. It kept flickering, so I was unable to get anything more.

For some reason, i want to say it has something to do with Thumbnail displays, as it seems to happen when I'm adding to the timeline (from Win Explorer - not VP's) while the thumbs are rendering in the project media window. I've switched that to file view (and limited the thumbs in timeline clips to both ends and center), but I'm not even sure that's the issue.

My display drivers are up to date - even though VP19 still lists the current driver in the update help window, though it's already installed.

Is it possible that something that "happened" in VP20 could effect VP19 somehow? This is a mess, because it sometimes even messes with other open programs - but it only happens when I'm working in VP - and generally when adding clips to the timeline.

HEVC legacy is checked and 3060i is the encoder.

Thanks for any help.

I am having the same issue with the latest build of VP19 (643). Screens go blank and my entire system "crashes". I have to do a full reboot. This is happening when importing clips. It did not occur during build 550. Unfortunate to hear it is occurring in VP20 still.

Just reverted back to version 4 in VP19 and importing works just fine. Bummer... I have to re-make my project with this version.

VP19 643 was VP20, we were beta testing VP20, but without VP20 features. When they do fix the crashing/corruption problem in VP20 we should get the fix on VP19. I think it's a very underhanded thing to do to customers, but frosty was praising them for it. The final version of VP19 should be the most trouble free and refined, not a brand new beta.

I hope we'll still get updates for VP19 man..

As VEGAS Pro 20 is the current version, I wouldn't expect that...

@ZachAtk1 have you tried the latest VP20 with the new update? I'm nervous to download and try it

@aggiezg05 you can download the trial version and see for yourself.

Please could someone tell me if build 643 is the latest for V19? I am on 643 at present, but I am getting a new build message whenever I open Vegas. Note, it says "there is an update for Vegas Pro 19.0", not "there is a new version of Vegas". My guess is that the message is misleading, and that it's referring to v20, however it doesn't give a build number, plus Vegas crashes every time it closes to update, so I can't even try it and see.

Like the OP, I'm experiencing much more frequent crashes with build 643 but I can't see how to revert to to the previous build. In any case, if build 643 is really V20 without the new features (hmmm . . . .), will reverting prevent me from opening files saved in 643 in the earlier build? Thanks for any advice.

Yes it is.

Like the OP, I'm experiencing much more frequent crashes with build 643 but I can't see how to revert to to the previous build.

You would need to uninstall build 643 and then install whatever build you want to use. You might also want to deactivate before uninstalling and then activate again on the older version.

For me, build 643 was the most stable version of VEGAS Pro 19. And VEGAS Pro 20 build 214 is the most stable version I have used in the past many years.

In any case, if build 643 is really V20 without the new features (hmmm . . . .), will reverting prevent me from opening files saved in 643 in the earlier build?

Actually new features were added in VEGAS Pro 19 after build 550. And if you go to build 550 or older, your build 643 projects will not open because of these new features. It's not "V20 without the new features". It's "V19 with new features added". See here for the list of new features and bug fixes:
