Odd, can't replicate that. Does it matter what kind of media is on the timeline? Any other clues? Can you paste in the addl. information from the crash report?
An actual 'my build is rampant" issue for once!? Lets see........
Hold the phone... Now that I try to grab the error report, seems not only is it working, it apparently decided to pop up on a different monitor than usual 😓
I don't usually have Vegas or it's windows on that monitor, outside of external previews... so hoping that was all there was to it. Will see, but I fear I may have jumped the gun on this one
