I haven't analyzed the crash log fully, but I had an issue which I need to share with other people in case it happens to you. Not sure why, but the downstream keyer malfunctioned and froze one of my scenes on top of all the other ones. Even restarting my machine (and OBS) did not fix the issue.
It was only through trial and error removing each plugin from the obs plugins folder that I was able to isolate the issue (since it was running fine in safe mode) and realized that it was an issue with having this on my machine. Certainly NOT the stress I wanted to deal with the night before a big event.
Just wanted to warn the community in case that happens to you down the line. I certainly don't have time to play around with why this happened, so maybe will try and experiment with it after the fact, but may have been a 1 in 1000 type of glitch. Even still want to make sure in case this happens to anyone else that they have a way to find out this information.
