Calendar no longer work on macOS Tahoe

Hello.


I just updated to macOS Tahoe and noticed that calendar no longer work with this error: "There was an unexpected error with the request (domain kEKAccountErrorDomain / error 9).". I tried closing it and reopen it a few times but it did not help. Is there a way to fix this?

If you go back to System Settings, there will be a couple of new terms and conditions that you'll need to agree to in order to get your calendars back. Worked for me.
