SUMMARY *** when I start plasma in x11 the panel appears like it should and behaves like it should. Clicking on a application shortcut will show the normal animation, but the application will never start. Adding a new panel, clicking a notification shortcut or doing any other action that would invoke in plasmashell starting a program stopped working. If I start a program by terminal or other means, they work fine. Restarting plasmashell to see the terminal output shows the following error when trying to start something: `file:///usr/share/plasma/plasmoids/org.kde.plasma.taskmanager/contents/ui/Task.qml:433: Unable to assign [undefined] to QString` nothing else comes up If I use Wayland, plasmashell works like it should. *** STEPS TO REPRODUCE 1. Boot the computer in x11 plasma 2. try to start a program through plasmashell OBSERVED RESULT plasmashell fails to invoke a program EXPECTED RESULT should open the program that was selected SOFTWARE/OS VERSIONS Linux/KDE Plasma: 5.26.5 Plasma on Manjaro
I notice now that something is really wrong with plasmashell as it is using up 3,2GB of RAM after start.
Can you try upgrading to Plasma 5.27 and see if it works now?
What apps are pinned on the task manager?
pinned apps are: Kontact, vivaldi-stable, konsole, dolphin, firefox, blender and obsidian There is no plasma 5.27 available even if I switch to unstable. I can't test this version.
I should clarify though: starting apps through the application launcher does not work either. Also if I right click on Desktop and select 'Configure Display Settings' - which should open up the system settings - that will fail to launch too.
It sounds like something very deep in your system is broken. Does `kcmshell5 kscreen` run in a terminal window work? Does `kstart5 kcmshell5 kscreen` run in a terminal window work? Please paste the output for each command.

Thanks. Can you run Plasma in a terminal window with `plasmashell --replace` and try to launch an app? Paste the error message when it appears in the terminal window?
Please attach your plasma-org.kde.plasma.desktop-appletsrc
Created attachment 156263 [details] plasma-org.kde.plasma.desktop-appletsrc attached the requested file opening an application -> spinning animation starts -> terminal shows `file:///usr/share/plasma/plasmoids/org.kde.plasma.taskmanager/contents/ui/Task.qml:433: Unable to assign [undefined] to QString` -> animation stops and application did not start
having a look at the plasma-org.kde.plasma.desktop-appletsrc myself I removed the [ScreenMapping] itemsOnDisabledScreens=... section. This seems to resolve the issue I was having
