My game is doing the same thing. I will get about 3-5 minutes into a game, and my computer will just turn itself off mid-game. It's not a temperature-related issue. One time, I got an error that said "memory management error 0 something," but it went away too quickly. BF2042 and BF6 are the only two games my PC won't run. My specs are a 5950X and 3080 Ti.
Same issue happened with me , it actually bricked my windows 11 . I also did a fresh intslal for windows and erased my data . It happened again . So people watch out !
I have rtx 3080 , with ryzen 9 5950x
