I have Vegas Pro 23 in the latest BETA (302) version and was having a horrible experience with constant crashes. I noticed that I went from occasional crashes to constant ones and couldn’t figure out why. After some analysis, I realized that Windows 11 had automatically updated to version 25H2, and I suspected that might be the cause of the frequent crashes. I tried to roll back to version 24H2, but since more than 10 days had passed, it wasn’t possible.
The only solution I found was to change the program’s compatibility mode to Windows 10 and run it as Administrator. It worked like a miracle — perfect, no more crashes at all. Later, I decided to disable the “Run as Administrator” option because drag and drop to the timeline stopped working.
However, for anyone using Windows 11 version 25H2 and experiencing frequent crashes, try setting Vegas Pro to run in compatibility mode for Windows 10 (it might not be straightforward, but if you ask ChatGPT, it can guide you step by step). Hope this helps!
