kalendar (22.12.0) using Qt 5.15.7

I have a crash for another reason but the wizard says my problem is a duplicated of this issue.
My problem is that Kalendar crashes when I click "Delete all the futures" when deleting an event that has repetitions: https://cloud.samuelezappala.it/s/yqzodW93fKrNjgf

I can't seem to open another ticket because plasma refuses to install the debug symbols.
