I have LS Dyna student version 2020R2 12.0.0 and when running LS-Run on my notebook I always get the following error:

I have already tried to uninstall and reinstall the software several times with no improvements. I have also tried and installed the same student version on other two pcs (another notebook and a Surface Go) and everything works fine.
All the three run Windows 11 Home.
Can someone help me with this?
