kalendar (22.12.3) using Qt 5.15.8

Right click on a recurring event, select delete and then select only delete current crashes the app. After restarting, the event is delete successfully.
On the notification tray if the option Restart app is selected and another recurring event is deleted, the app freezes and doesn't respond for a while and then crashes. 
This bug occurs every time.
