Discover 5.14.4 on Manjaro is unusable. 100% of the time it hangs on launch and the UI freezes within moments, usually while loading the Featured list. The following is printed to the console: $ (master) /usr/bin/plasma-discover file:///usr/lib/qt/qml/QtQuick/Controls.2/org.kde.desktop/TextField.qml:57:5: Unable to assign [undefined] to QQmlComponent* invalid kns backend!
