Hi, I had a similar issue / behaviour when starting AusweisApp2. Although the cause was a little different in my case. The reason mentioned here is
default 2020.09.27 21:36:59.329 47262 W unknown(unknown:0) : QQmlApplicationEngine failed to load component default 2020.09.27 21:36:59.330 47262 W unknown(unknown:0) : qrc:/qml/+desktop/main.qml:171 Type ConfirmationPopup unavailable qrc:/qml/Governikus/Global/ConfirmationPopup.qml:7 module "QtQuick.Layouts" is not installed Installing 'qml-module-qtquick-layouts' fixed this problem for me. Maybe that package should be part of the dependencies as well. Regards, some pseudo anonymous person (mainly for spam porpouses)
