Hello everyone, I just signed up to say that I found a fix that worked for me after all the above didn't so if you're on my boat, I found a vtube software that was the problem. So not necessarily VseeFace, look for something similar to vtube or anything with camera tracking and try uninstalling it to see if that helps. I have some other softwares like canon utility but they had no effect on obs crashing.
Also wanted to say that obs used to completely crash when closing aswell, always had to end process, now it's fine
