BF 6 started crashing my PC after Season 3 update

As I mentioned in the title, my PC started crashing when playing BF6 (Intel 13900k, RTX 3080, 32 GB DDR5) 

It was runing relatively okay (rare game crash, but PC was ok.) with high graphics. But now after 30Mins my whole system crashes. I tried lowering my graphics, also ran some 3d Benches to make sure my System is stable. The game has become unplayable for me. Any suggestions?
