[SOLVED] Plasma 6 System Settings not launching

I updated to KDE Plasma 6 a couple days ago when the update was pushed to Arch.
So far everything's been fine, except for the System Settings app which won't launch:

$ systemsettings
QQmlComponent: Component is not ready
"qrc:/qt/qml/org/kde/systemsettings/Main.qml:25:5: Type SideBarItem unavailable"
"qrc:/qt/qml/org/kde/systemsettings/SideBarItem.qml:12:1: Type Kirigami.ApplicationItem unavailable"
"file:///usr/lib/qt6/qml/org/kde/kirigami/ApplicationItem.qml:75:1: Type Kirigami.AbstractApplicationItem unavailable"
"file:///usr/lib/qt6/qml/org/kde/kirigami/AbstractApplicationItem.qml:107:5: Type KT.AbstractApplicationHeader unavailable"
"file:///usr/lib/qt6/qml/org/kde/kirigami/templates/AbstractApplicationHeader.qml: module \"Plasma\" is not installed"
Fatal error while loading the sidebar view qml component
KCrash: Application 'systemsettings' crashing... crashRecursionCounter = 2
fish: Job 1, 'systemsettings' terminated by signal SIGABRT (Abort)

I have tried re-installing systemstettings and rebooting, but neither have worked.
Any suggestions as to what might be causing this issue?

Re: [SOLVED] Plasma 6 System Settings not launching

A similar error is also occuring in kdeconnect:

$ kdeconnect-app
QQmlApplicationEngine failed to load component
qrc:/qt/qml/org/kde/kdeconnect/app/Main.qml: module "Plasma" is not installed

The process is not killed but no window opens.

I have the latest versions of both packages - systemsettings 6.0.1-1 and kdeconnect 24.02.0-2

Re: [SOLVED] Plasma 6 System Settings not launching

Okay, I've solved the issue.

$QT_QUICK_CONTROLS_STYLE was set to Plasma, hence kirigami is using /usr/lib/qt6/qml/org/kde/kirigami/styles/Plasma/ to style the system settings. For some reason, libplasma isn't providing a 'Theme.qml' file in this directory, unlike the 'org.kde.desktop' style and the 'Material' style.
Thus, unsetting $QT_QUICK_CONTROLS_STYLE or setting it to Material or org.kde.desktop solves the issue.

Re: [SOLVED] Plasma 6 System Settings not launching

I am facing exactly the same issue after switching to a Breeze light global theme.

Solved it by reinstalling kde-install-config.

Thanks in advance
