Thunderbird freezes

I keep getting a message "Item changed on server" with two buttons to press.It relates to one change I made to my Calendar in December 2022. If it appears when I first switch on, I can shut it down but later on it often freezes and I can't use either button. I have to go into task manager and shut Thunderbird down. This happens at least once a day.

How can I solve this permanently?
