Unreal 4.26 is not opening in my RTX 3090 gpu machine

Hi there I was using unreal 4.26 and I started having problems when trying to build a landscape using UWIS and 4k textures. After a few minutes of material painting on the landscape the graphics card would shut down giving me the D3D error. after some trouble shooting nothing seemed to work. as part of the trouble shooting I activated virtual textures following a video on youtube given that I was at the end of my tether with this and now 4.26 does not work. It stays stuck at 39 percent when loading. I re installed unreal and 4.26 and the issue persists. I deleted the projects and it wouldn’t allow me to create a new one by getting stuck on 39 percent. Please advice.
Thanks in advance.
