Apple Contacts launches but will not open
I am unable to access my contacts on my Mac. The app launches, but then will not open -- I cannot see any names/addresses. The Contacts app does appear in Force Quick. Force Quit is the only way to quit the app.
I am running Big Sur (11.4)on a Mac Mini M1.
I've only had this computer for 2 weeks. Contacts was working fine for the first 10 days before the problem appeared.
Any suggestions are appreciated.
Thanks!
Mac mini, macOS 11.4
