Everything was totally fine when I used Ubuntu 21.10. But after I upgraded to Ubuntu 22.04, Gnome Calendar stopped to sync my events of my Google accounts. I was not getting anything at first but then, I purged it and reinstalled it. Then connected my Google accounts again in gnome-online-accounts (goa). Then I launched the app from terminal and I found the issue. It's showing,

I am getting no fix of it. I have tried multiple times. Any fix of this???? Also, when I tried to use app password as I have 2fa on, goa forces me to use the password of my Google account. I have tried the v42 of calendar in Fedora and it works fine.
