Windows 7 Professional with all the latest updates.

I tried the following Illustrator Versions:

V 23.0 and V 22.1

Illustrator opens as usual and I see the overview screen. When I select a file or try to create a new one it just loads forever. Nothing happens. Also in task manager there is nothing going on. No high cpu or memory usage.

I worked for years with Illustrator on this machine. Version 22.1 always worked. The issue appeared after updating to the latest version. I also uninstalled the latest version but the issue still remains. Any idea of how to track down this problem?
