Calendar isn't displaying events after most recent update (78.4)

Thunderbird Calendario

An update overnight appears to have broken my calendar connection. I've restarted Thunderbird. Resync'd the calendars. [https://www.screencast.com/t/7IqyRQRY.../7IqyRQRYz0wm]

These are Google calendar's that worked until today. Appreciate any suggestions. I'm off to remove one of the calendar's and attempt to re-add it now.

Thanks.

So, it appears that updating to latest version just disabled the calendar add-on. Looks like I need the prior version of Thunderbird so I can bring back my calendars.

Anyone know how to roll back an update?

I think you just need to install version 78.0.1 of the Provider add-on:

https://addons.thunderbird.net/en-US/thunderbird/addon/provider-for-google-calendar/

Drag the Download Now button and drop it onto TB Tools/Add-ons/Extensions.
