akonadiserver (5.22.2 (22.12.2)) using Qt 5.15.8

The crash happened while closing a window (Todoist) shortly after another application (Vivaldi Browser) was closed. Unusual prior behavior was that hidpi scaling was not correctly applied, meaning those two applications looked tiny on a 4k screen. Changing the global scaling via settings did not help, which is why I closed those windows.

akonadiserver (5.22.3 (22.12.3)) using Qt 5.15.8

After KDE Plasma freezes while using ALT + TAB to switch the tabs because plasmashell isn't reacting, there is a slighty chance that Akonadi is crashing
