I've just been watching someone stream Jedi Survivor on PC on Twitch and they were having huge problems with OBS crashing. They solved the problem by using two GPUs, gaming on one GPU and having OBS use the other. I think the gaming GPU was a RTX 3080 Ti and the OBS GPU was a GTX 1060 but I'm not sure.
I hope this helps someone.
