The game just crashes for no reason

I've got BF6 crashed for many times. I've got an RTX4080 Super and a Ryzen 7700 onboard. I tried to install the latest Nvidia driver (580.97) and then got a BSOD in a minute after the match started. Then I switched back to the 577 driver that seemed to work better. I had a pretty good 5 hour long session with it on Friday having only 2 crashes when the game just suddenly closed. However, on Satturday the game kept crushing every match I played. I tried some other tricks like adjusting the CPU frequency for 100 MHz, adjusting the GPU and VRAM frequency for 100 MHz and some other stuff, which made no effect on the game stabylity.  Then on Sunday the game ran pretty smoothly with no crashes for about 5 hours. Then I took a break for a few hours shutting the PC down. When I started a new session the game crashed twice when I played Conquest matches. When I played Domination, Deathmatch and King of the Hill matches I had no crashes at all. So i suspect those crashes could be caused by unstable internet connection speed which is critical for playing bigger maps wihth many players. What internet connection speed do you typically have? Do you use Wi-Fi or Ethernet?
