Mathematica 12 was working fine, but after recent updates (Nvidia drivers and Windows 10) the kernel will load happily, but when trying to load Mathematica the screens hang and I'm greeted with a blank white panel in their place.
AMD CPU, NVIDIA 3080 GPU, all latest drivers/updates installed.
I suspect it's maybe a DirectX issue from the thread below, but can't quite pin down how to resurrect it. I've reinstalled Mathematica and still no joy.
I've tried to force it to run in difference DirectX versions, but I'm getting the same problem.
I wasn't sure of a couple of parts within this potential answer, how to specifically edit the Environment Variables.
