I have tried running FLUENT by itself as an administrator, but it still experiences the same problem. I have also tried uninstalling and reinstalling ANSYS, but that does not work too.

To add on to this, I have also ran the following commands on Command Prompt, based on a similar post made on the forum:

set HOOPS_PICTURE=dx11
"D:\Program Files\ANSYS Inc\ANSYS Student\v232\fluent\ntbin\win64\fluent.exe" 3d -t2

To which Fluent did open but with the following error message:

I have tried to set HOOPS_PICTURE to opengl2, msw/win and opengl but to no avail. I have also updated the graphics driver to the newest NVIDA Studio and Game Driver but am still unable to open Fluent properly.
