I have also noticed events don't work.

I might be dependent which sync method and backend you are using.

My Thunderbird is synced to my private Nextcloud, and I have not experienced any problem with then new version. Thunderbird recently got native support for CardDAV. Before, using the TbSync addon, it was less stable.

I am using the sync built into Thunderbird. In fact, this is the reason I switched from Seamonkey to Thunderbird. There was an add in for both to sync with the Google calendar. However, after Google changed the connection security, it stopped working. I then notice Thunderbird could now sync on it's own, but Seamonkey couldn't. The calendars sync, but I have to create the events in the Gmail calendar, using a browser or the Android apps.
