NVIDIA Graphics Driver Installed Cannot Open Application Windows

So following this guide:
https://neowutran.ovh/qubes/articles/gaming_windows_hvm.html

I managed to pass-through my GPU to a Fedora standalone HVM. The VM will work normally but only before installing the NVIDIA graphics driver. Afterwards, no applications will open and I can only access the VM via SSH.

Any help would be appreciated
