I’m having issues creating any new projects.
Unreal engine will open, but creating any new projects results in a crash at

I’m trying to diagnose this issue, and I noticed that it’s referencing the D drive. I have a D drive, but there isn’t anything Unreal related on it, neither is Unreal installed on this drive.
I tried a clean installation of NVIDIA Studio Driver, with no resolve.
I tried uninstalling/reinstalling UE5.3.2, with no resolve.
Dism, sfc, chkdsk turned up nothing.
Environment:
Windows 11
ROG STRIX Z790-E Gaming Wifi II
i9-14900K
192 GB Corsair Vengeance RAM
RTX 4080
1200W PSU
No overclock, plugged into a UPS.
I had an issue just a week ago, where I had to get the UPS because of computer instability with UE5, but that had resolved it at the time. I just started experiencing this today.
Any help would be appreciated.
