Thunderbird 115.6.0 (64-Bit) is no longer syncing with Google Calendar.

I do not know since when, but recently added dates in Google Calendar are not show in Thunderbird calendar and vice versa. 

I've tried to setup new connection between Thunderbird and Google, this seems to work, because I got question on smartphone (authenticator app) to allow new connection. But the dates are still not synced. Even forcing sync does not do anything. Same things happens on two Windows 10 64bit computers, but also on Linux Mint. Any advice? Thanks.
