I don't use video editing at all these days and havnt for years but today I wanted to use it. Last time I used this program was when my computer was running Windows 10. It's now on Windows 11 Home. However, upon restart after installing Vegas Pro 20, it now crashes every time I run the program. Here's the info I get... I can't be the only one whos had this problem and would be grateful for a fix if available.

Thank you

I've just installed a trial version of Vegas 23 and I have the same problem. Here's the report. Please not my computer hasn't changed since Windows 10 except C: drive is now a 4Tb SSD + running Win11 upgrade.

Solved! I read on here someone saying they found Studio One had altered (somehow) C++. I've been using Studio One (now Fender Studio Pro) a lot recently. So I downloaded and installed C++ again and Vegas 20 & 23 both open fine now.
