GPU Crashed or d3d Device Removed (STILL)

Hello everyone.
Every time I launch unreal 5.5 i get gpu crashed or d3d device removed.
It has been an on off problem in unreal since August.
Now 5.5 isnt loading at all, I made this thread before and I was hoping to be able to start my project again when 5.5 came out.
Still have the problem.

Ryzen 9 5950X, RTX 3080 10 gig, 64 gig Fury-X Ram, 2 Tb Fury Nvme m.2, 8 tb ssd.

Heres my old unanswered thread.
I am now 5 months behind with my project.
I have bought ALL new hardware for my PC.
I have tried uninstalling epic launcher and engine (40+ times), reinstalling windows (10+ times).
I have launched brand new projects. I have completely restarted my project twice before.

Unreal is quickly looking like unusable trash that I have spent over £1500 on assets for from marketplace.

Any help at this stage would be great. Considering the 400+ crash reports I have sent epic (with no reply) I am considering moving to unity.

Id also like to add. Where would I go to get all of my assets refunded from unreal engine?
Their platform is unusable.
