Trados Studio crashes without message when creating a project

I installed the new licence 2024 (perpetual) without any problems last Wednesday and even processed my first project. However, since Friday afternoon, I can't create any new projects. The programme closes during the project creation phase (last window) and no error message appears. I have already uninstalled the licence and reinstalled it, but it still doesn't work. I have searched online, but without success. Can you please help me?
