Black screen of death after 10 minutes

Hello everyone,

End of April I upgraded my PC. Everything went well but since Sunday I can't play Total War Warhammer 3 anymore.

The game starts and runs for approximately 10 minutes before it freezes. Then the game freezes and crashes PC.

I get a black screen of death wit the message: "your device run into an unexpected issue and needs to restart".

The PC restarts but when I try to play the game I get the exact same issue.

My specs are:

Asus Prime 450b MKII

Intel Arc 580b

AMD Ryzen 7 5700x

32gb DDR4 RAM.

I have a 850 W gold plus PSU.

All Drivers and Windows are up to date.

Can you guys help me ?
