After auto-update in Thunderbird 128.8.1esr all calendars did not work. The Google Oauth2 password pop-up gave an error "The browser you're using doesn't support JavaScript, or has JavaScript turned off..."
I could resolve this by switching the advanced setting "javascript.enabled" from false to true, and after re-activating the calendars I could swith it off again with no further issues so long.
So it works fine for me again - thanks a lot to Philipp!
