Nokia 6.2 stopped syncing events on Google Calendar

I use Google Calendar as the default calendar application.

Google Calendar used to show all events from my several accounts (corporate office 365 account and personal hotmail account) but suddenly calendar is not updating and some events are missing, although in my outlook client all events are shown. So, I have to open Teams app to check my corporate calendar events.

Nokia 6.2, model TA-1187, Android 10

I appreciate all the help I can get to solve this.
