Im not sure how to fix this

Hi so I keep getting many different EXCEPTION_ACCESS_VIOLATION errors Ive been looking through the forums all day to figure out what I could to. I thought I could have insufficient ram, but at the same time I dont think so. Ive tried many different fixes like resetting BIOS, setting NVIDIA control panel global settings to default, verifying files, uninstalling and reinstalling UE5.4.3, and changing specific settings. This isnt all the errors Ive gotten, but its a few of them.

My PC specs are:
Windows 11
NVIDIA GeForce RTX 3070
I7
16GB Ram
1T SSD
