Yeah, just a shot in the dark. Sometimes these small indie games can put more stress just because they are unoptimized though. My Unity favorite was my old 6700xt trying to do 1,500 fps because there was no cap on the game. I'd just hear the fans fire up for not very good game graphics heh.I run games that have much higher loads than this game ever could. Absolutely no reason as far as hardware, drivers, or OS that my entire PC should be hard crashing from this little game.
You played any other UE5 games? Palworld?
