I believe this problem has little to none todo with GPU.
I had a working version of Ansys 2021 R2, that was until I installed new version of Solidworks. This effectively caused me to have this problem.
Ansys could remedy this problem by a) adding a repair feature, which could re-install the necessary extra files to system folders, or even better b) stop using system folders altogether and install and use files only from Ansys folders.
