Games don't load and get stuck saying stopping
I just recently bought a new PC and I've gotten my PC how it was on my old one. however after downloading steam and my games i tried to load Palworld and SAO Fatal Bullet but all i get is a black screen, before it brings me back to the library. It proceeds to stay on stopping after pressing stop as if the game is open but i can't access the game. I've tried a few troubleshoot methods online that didn't work and i just reinstalled steam today and tried Palworld again but it has repeated not loading on black screen for a bit, and proceeding to say stopping constantly after pressing stop. This didn't happen on my old PC which could load the games but not play them well.

I'm confused any help or advice would be greatly appreciated.
