UE 5.6.1 Unhandled Exception: EXCEPTION_ACCESS_VIOLATION writing address 0x0000000000000000

Currently, I am messing with a cross-hatching shader and any time I screw with my curve graph to edit the shader it crashes with what I put in the title. Please help lmao

Too add more information now, any time I do anything in unreal engine, it just crashes with any error code relating to graphics/memory. I have uninstalled and reinstalled my graphics card drivers, did a memory check, uninstalled unreal and deleted all the different cache or folders it left over, and updated windows and every other thing on my PC, and lastly I have done many image repairing, but nothing is wrong.
