Problem
Opening share permissions on a file provider item always failed now. There always comes up an error stating the user does not have sufficient permissions.
Underneath, the file provider UI extension fails to fetch the XPC service based on the selected file provider item.
Solution
I have written a blog post about the problem almost 2 years ago:
https://i2h3.de/filemanager-throws-error-on-getting-file-provider-services/
I do not know why it became a problem now. Maybe due to latest security updates by Apple which changed the underlying system for non-sandboxed apps.
