V1.6.1: GUI main window not shown on Kubuntu 20.04.3

Hello everybody,

The main GUI windows is not presented on my Kubuntu 20.04.3 system. I tried the appimage version as well as the ppa - same result.

The Cryptomator icon is shown in the right hand bottom corner of the KDE control panel, right click presents the menu (German version) “Anzeigen/Einstellungen/Alle sperren/Beenden”.

“Einstellungen” presents the setup options, “Anzeigen” does not work.

Any idea how to solve this problem?
