Hello!
I've been struggling with that issue and I've tried a lot of recommendations but this is what solved it on my computer (CPU 13900k, MB MSI PRO Z790-A WIFI, Video card MSI GeForce RTX 4080 Suprim X and RAM G.Skill Trident Z5 RGB DIMM Kit 64GB, DDR5-6000):
Underclock the CPU slightly.
I used Intel Extreme Tuning Utility for the ease of use. You'll find a brief explanation in those two pictures that I attached.
I hope it works for you. I recommend to work your way up by adding more clock once you've found a working clock speed for Battlefield 2042.
This has been the one thing that has worked for my issue that started last week. i9-14900k, 32gb ram, 3080 FTW, I would get blue screens or directx out of memory errors. Reloaded everything, using Intel Extreme Tuning Utility was the only thing that made things work, I knocked the performance core ratio down to 56x vs 57x and everything has been great.
