Splash Screen Crash

Hi everyone,

One of our developers experiences severe issues with his installation of SolidWorks 2023 SP5. On start it just crashes after the splash screen appears for about 2 seconds. Event log just says that SolidWorks.exe crashed. The computer in question is a HP Z2 Workstation with an Nvidia Quadro 4000 grapics card. As far as I could determine the equipment is certified by SolidWorks. Everyone in the room has the same equipment but only one guy has the problem. I already tried updating the graphics driver as well as a full clean uninstall and reinstall of the software, according to this website

 Nothing helps.
Any ideas?
Thanks
