UE 5.4.4 Editor and games crash on load, but doesn't with earlier (5.3, 5.2, 5.1, 4) editors.

After updating to 5.4.4, the editor crashes on a default empty level. After compiling shaders it starts to load all the editor components but then crashes when at “Loading Flatten Material”. It seems like the monitor just goes off like the GPU is crashing. I read the updates on similar posts and tried everything. I’ve updating all the drivers, and even tried downgrading to older reportedly reliable drivers. Updated my BIOS and AMD Chipsets. I disabled ULP (ultra low power mode) and made a few registry edits per others suggestions. I tested memory. I tried clearing AMD’s shader cache but there were a few files “undeletable”, I’m guessing in use even after resetting. If there’s another way to do this, please help a guy out. Thanks!

I have an AMD Radeon RX 6600XT and Windows 10, 32GB Ram, 8GB Dedicated VRAM/24GB available. 5.3 and older editors launch fine.
