@MrGazule Can you please provide exact reproduction steps?

Is there anything special? like a space or & in the name of groups if you use group shares?

I launched the update to version 12 via the web interface, no error appeared. (I have the logs of the update if necessary)

I managed to target the problem, it would seem that the group shares the problem (only on calendar). If a direct share with another user is applied it works.

Ex: sharing with the group employees no one sees the agenda;
Share with Mr X sharing works

And this error appears on Evolution software
