Message: app is damaged and can't be opened. You should move it to the Trash.

This would be a message we saw from time to time that tended to be from the Mac App Store and related to 1Password 7. Is 1Password 8 working for you? Looking at your specs you're up to date thought I would mention 13.3.1 (a) if you've not had to install it.

It might be that a portion of 1Password 7 was left running. Can you look up in the menu bar for our helper and right-click and select Quit 1Password completely? * 1Password 8 only uses the word Quit. A restart should also free up any stuck cobwebs. If possible check the trash and make sure 1Password 7 is not present there. You could also consider emptying it.

Thank you... I don't know which step worked... empty trash, Quit 1Password, system update or restart because I did all at once.
