Teams not syncing with Calendar App on MacOS

In recent weeks, my Teams calendar has stopped syncing with MacOS Calendar App. It used to work fine, but suddenly stopped syncing.

Teams continues to sync with my iPhone Calendar app. So it must be something to do with the link from Teams to MacOS on my laptop.

Am using MacOS Sequoia 15.2

Have tried the usual:

1) deleted and re-added the Teams account containing the calendar I want to sync

2) manually refreshed the calendars in the calendar App

3) closed and opened Teams and the Calendar Apps.

nothing works.

Any ideas?
