When I press the Render As button, Vegas 22 hangs, then crashes. I never get to see the Render As dialog box
I've seen this in V21 as well, but with V22 I'm seeing it more often. Today, it was happening consistently and couldn't render out my project. I think because I am using more HEVC.
This issue keeps coming up...today I have restarted Vegas15 times in trying to get the "render as" dialog box to come up. Yes C++ and .Net is up to date...frustrating.
There's a render as crash that's kinda similar that has plagued my system for years... I've always found that if I open a blank project first, drop any media onto the timeline so i can click render as, then do so... it opens the dialogue just fine... but if I don't, it'll crash, but only on my desktop. If I do any sort of complex editing, and forget to do that step first, it will crash.
So, I always start a new project, open the render as dialogue, close it, then open my project that I'm trying to render.
If VEGAS is crashing when trying to open the render dialog, it almost never is a problem with the media in the project, since the render dialog does not try to access the media until you execute the actual render.
In this case, it is more than likely a problem trying to load on of the render plugins...often due to an issue with the GPU or Windows. In this case, the problem seems to be with the Video for Windows plugin based on the the log you provided. That would indicate that there is a problem with OS. You could probably get around this by removing or renaming the avi plugin (aviplug.dll), since that is what uses Video for Windows.
This might be caused by some incompatible AVI codecs being installed on the system.
Renamed the original aviplug in the C:\Program Files\VEGAS\VEGAS Pro 22.0\FileIO Plug-Ins\ folder and downloaded the new file (I didn't want to be without the aviplug.dll).
