I've got BF6 crashed for many times. I've got a Ryzen 7700, an RTX4080 Super, 32GB RAM onboard, Gigabyte b650m Aorus Elite AX motherboard (F34 BIOS), 850W Gold PSU. For 3 times the game crashed with an DX12 error report. Then I switched from 580.88 Nvidia driver back to the 577 driver which seemed to work better. I had a pretty good 5 hour long session with it. The next week 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 having 160FPS in QHD with it on Friday having only 2 crashes when the game just suddenly closed. GPU temperature was about 65C, CPU temperature was about 60C. However, on Saturday the game kept crushing every match I played. Some times it looked like I just suddenly quit the game, the other times my PC froze with a frozen game screen or a black screen. I tried some other tricks like adjusting the CPU frequency for 100 MHz, adjusting the GPU and VRAM frequency for 100 MHz, turned the exploit protection full off for BF6, switching from Steam to EA app back and forth, turning the antivirus off and some other stuff. However, it made no effect on game's stability and it kept crashing. Then on Sunday the game ran surprisingly 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 concluded there were some issues in the game which caused instability.
