I have a very strange windows/game problem.

I only have this problem with 1 game. I have also played this game previously, the only difference being I switched from my Intel CPU and Nvidia gpu to AMD. No other games cause this problem or have anything similar.

Whenever I click play on Steam, on the game Middle Earth Shadow of War, my pc bricks itself basically. The game doesn't launch, and if I had task manager already open, it shows the game using 0% everything except 20mb ram.

If task manager was closed and I try opening it, everything has no icons and shows 0% usage on all boxes. I can't open any other applications, I can't ctrl alt delete as I get an error, I can't even click the shut down/sleep/restart buttons as they don't do anything.

I have tried reinstalling the game, deleting the exe and verifying the game. I have tried running as admin, which leads to the yes/no prompt not appearing and me having to hard restart my pc. I've tried running in compat mode, disabling full-screen optimizations, and tried deleting the config files. Reinstalling my drivers and cleaning with DDU just in case also did nothing. I'm stumped. I can't for the life of me figure out what's causing this.
