Battlefield 6 keeps crashing the game or rebooting PC

Since yesterday, my game has been constnatly crashing 5-20min throughout a match without any error code or similar to look up. Even worse is that sometimes it even makes my entire PC restart. It reached a point where the BIOS would automatically do a safe start and upon launching the game again it told me that the save files were corrupted and had to be overwritten.

I tried repairing the game through the EA App, checked if all the cords are plugged into my PC properly, updated my graphics card and booted the game as an Admin, however, all those options failed.

Has anyone else experienced similar issues?
