Error with Calendar App


I’ve just created a new calendar and when I try to access on desk I’m getting this:

pymysql.err.OperationalError: (1054, "Unknown column 'start' in 'field list'")

I’ve reinstalled the app, bench migrate, and nothing. Get always the same issue.

Any idea?

By the way, events are displayed as Undefined events on default calendar. Its event has their own title and filled fields.

Thank you.
