Hi there, so I get issues with my UE4, like let’s say i decide to click a asset or maybe an edit option or anything, I get a black screen. buggy screen. I have reinstalled UE4 multiple times and on different drives. My hardware is 8GB RAM, GTX 1650 SUPER, R5 2600X. It worked fine up until 3 months ago.
Do you have updated your GFX-Driver? Some more Detqails about what you changed would be great.
I tried that as well.

its like the error i have. could it be you use rtx/raytracing?
No that wouldn’t cause my UE4 to have a stroke.
okay, cause you are using the DX12. I had nearly the same error and only if i use DX12 with raytracing. After i Switched to Vulkan as the default RHI everythings fine. Maybe you should try that.
I just disabled raytracing, so far so good.
fine 
if you want to use raytracing, maybe vulkan is the beter choice until it may solved why dx12 got this problems.
