Unable to Build Unreal from Source

Assuming you followed this guide: Building Unreal Engine from Source | Unreal Engine Documentation

and D drive is not your main drive where Windows is installed (But, D: has Desktop, so… /shrug).

I would suggest you try a fresh reinstall. (and if D is your main drive, do it on another one)
