Shortcuts for mac broke

Whenever I run a shortcut on my iMac (End 2015, Monterey) I get the message “could not communicate with helper application”.
The app is unusable.

The problem occurs in save mode as well.
I am using shortcuts a lot and this is a big problem for me.
I don`t know if I can reinstall it after uninstalling it. So did not try that.

Any suggestions, what the problem might be?

Best regards
