I was trying to sync my google calendar with gnome-calendar, for that I added my accounts to ubuntu 20.04 but gnome-calendar didn't sync with them(don't know why) and after than when I restarted my laptop I saw that credentials for all of the accounts were expired.
Any clue why is this happening and why I am not able to sync the calendar?
In my case, i could fix a similar looking problem by executing
$ /usr/libexec/goa-daemon --replace
See this comment on a Red Hat bug report about goa-daemon.
I found this may works for you .
Try this:
Remove you Google account from Gnome Settings
Remove ~/.cache and ~/.config/goa-1.0
Sign in again for your Google account from Gnome settings, and give it some seconds to sync
Logout and login or reboot.
