PC Crashing

I have been trying to resolve an issue for ages now. The standard troubleshooting doesn’t work. 

the game will crash after 2.5 minutes after loading the game up. I did originally have ea play pro version, then I also downloaded the game on steam, to see whether that stability helped (no change).

the spec of my pc is below (I know nothing about PC’s). 

CPU - intel core i9-12900kf 

GPU- GeForce RTX 3080

Motherboard - MSI Pro z690-P-DDR4 (MS-7D36)

RAM - 16gb

Power supply - MSI MPG A850GF - 850W, 80+ gold, fully modular 

Typical temps CPU idle - 24-33°C, motherboard - 30°C, GPU idle - 41°C

please help a guy out!!
