I'm on Ubuntu 20.04 with gnome-calendar 3.36.2 and have the same problem: Google calendar did not sync.
Then I removed the cache in "~/.cache/evolution/calendar/", and gnome calendar showed no appointments at all (as expected).
Clicking the "sync now" menu item changed the calendar icon briefly to a checkmark, but "journalctrl -f" said:
