Rhino 6.21: Crashing over and over again

Hi,
could you please help me? This afternoon, I updated Rhino 6 for new version and since then, it crashes even if I just want to create a new file. I tried to uninstall the programme, but no success.
I have MacBook Pro (13-inch, 2017, Two Thunderbolt 3 ports) and here is the Crash Report:
