Thanks a lot for this, I can’t believe I spent so much time having this dumb issue :man_facepalming:

I had this happen to me randomly recently after the calendar had been working fine for a good few months after a hass restart. My solution was to move the .google.token file (which was not empty and appeared to be just fine) to a different file name, then restarted hass and did the process to reauthorize the app using https://www.google.com/device again, and everything went back to normal and a new .google.token was created… Not sure why it crapped out all of a sudden, but that was the fix.

Deleting my (hidden) .google.token file and reauthorising via the notification that pops up fixed a similar issue for me.
