fecfek,
We appreciate you for getting back to us and for providing us those details. By any chance is your Apple ID account under your Mac user account managed by an adult or family organizer for Family Sharing within Screen Time? If so, we suggest to have the family organizer turn off Screen Time: Turn off Screen Time on your Mac
If your Apple ID account is not managed by a family organizer, we recommend to restart your Mac in safe mode. Once you're in safe mode, please restart your Mac as normal and see if you continue to experience the same behavior. Here's how to restart your Mac in safe mode: How to use safe mode on your Mac
Please keep us posted with the results.
Best regards.
