I found a workaround for now:

Delete your saved tokens via Options, Security, Saved Passwords. Delete all OAuth tokens for Google Calendar then closed TB.

Open TB. You will get a popup for each Google Account associated with the calendars you have. Pay close attention to the account name and authorise only the first pop-up, then CLOSE the rest, and close TB again. Repeat this process for each Google Account until all are authorised.

Hope that helps everyone
