I was crashing constantly with very similar hardware, but for me it was main menu or in game, what fixed it for me was adding -bEnableGlimpse 0 in the launch options box for the game in steam, right click game and select properties, you should see the launch options box, If that doesn't fix it use chat GPT to analyze your crash dump that is located in documents/battlefield 6/crash dumps, You will need to open the crash dump first with a free program called WinDbg from the windows store, select file, then open your crash dump file and click !analyze, Paste the results in Chat GPT and tell it to try and figure out why your game is crashing
