I've had a similar problem with a client using an earlier operating system. We had to resort to Apple Tech Support on a telephone call.
Now that you've updated to the most recent operating system, I suggest signing out of your Apple ID and then signing in again. To do this, in System Settings tap your name. Scroll to the bottom of the pane and click Sign Out.
Note: if you use iCloud Drive for storage, or Mail, Contacts, Calendars, etc. you will be asked what you want to do with that data before logging out. Here's more info.

If that doesn't clear the error, I would suggest calling Apple Support. They will connect you with the team that specializes in Apple ID. The geniuses at the stores are not allowed to do Apple ID stuff, so I'd start with a call.
I run a habit tracker as an apple watch complication that now requires confirmation that reads: "Allow to access "(null")"?
This started a few months ago when I was on Beta but it continues now that I am no longer on Beta.
Any suggestions?
