EXCEPTION_ACCESS_VIOLATION ?

Hey! last resort because I genuinely cannot find a fix for this. I get this error on both Marvel Rivals and Subnautica 2; I've tried launching rivals via steam and epic, with the same error. Both subnautica 2 and marvel rivals give me the same ue5 crashlog stuff just under different codes that will be pasted at the bottom of this post. I'm able to play other UE5 games like palworld and the finals just fine with no issues.

Subnautica will not launch at all, but Marvel Rivals will eventually launch if i just keep pressing play and closing the UE5 error log- usually on the 10th-15th time it'll launch and once it does I have 0 issues (no lag, in-game crashes, etc) it's just getting it to launch thats the problem.

Solutions I've tried (this may not be all, these are the ones I remember doing)

• updating my BIOS to the latest version
• installing chipset update from MSI
• Turning off XMP and running RAM at default speed
• manually underclocking RAM to 4000
• Rolling back AMD...
