Unreal Engine 4 - GPU Crashed or d3d device removed UE4

well, unity is not free, the free version of unity is not even having the features that unreal have for free, and also unity is not made for archviz. It’s made for mobile games and pc game creation witch is not wrong but I want to be able to use a raytraced light build since the old cpu method is not working for me and not giving the right result. I have 1660 super that should be able to run DXR/RTX. and no im not using the other archviz software like blender that requiers a rocketr scientist and i don’t have lumion since I’m not a millionaire that can throw up 4.000 USD right i in the place. i have same issue with 4.26
