Shortcuts for mac unusable because of "Couldn’t Communicate With a Helper Application"

Can anybody give me a hint?

the shortcuts app on my mac (2015 running Monterey) stopped working some days ago.
When I opened it I had a spinning beachball and had to force quit the app.

I solved this problem today by just starting up in safe mode.
Now every time I run a shortcut from the app I get a " Couldn’t Communicate With a Helper Application" error message.

I depend heavily on shortcuts in all of my workflows.
I already searched this forum, reddit etc. for answers but could not find anything.

please help!
Best regards
