Have you verified that there wasn't a zombie process for it still running in the background, preventing a new instance from being launched? Does it print anything in a terminal window? Does it work on Wayland?

> Have you verified that there wasn't a zombie process for it still running in the background, preventing a new instance from being launched? That's probably the case, roughly speaking. Not exactly a zombie, just a running process without a window. When I kill that process and restart "plasma-systemmonitor" from Yakuake, no window shows up and I see the following on the terminal: ``` $ plasma-systemmonitor QQmlApplicationEngine failed to load component qrc:/qt/qml/org/kde/systemmonitor/Main.qml:33:26: Type GlobalMenu unavailable qrc:/qt/qml/org/kde/systemmonitor/GlobalMenu.qml:42:9: Type NewStuff.Action unavailable file:///usr/lib64/qt5/qml/org/kde/newstuff/Action.qml:184:13: Type NewStuff.Page unavailable qrc:/qt/qml/org/kde/newstuff/Page.qml:148:5: Type NewStuff.QuestionAsker unavailable file:///usr/lib64/qt5/qml/org/kde/newstuff/QuestionAsker.qml:134:23: Kirigami.BasicListItem is not a type ``` Haven't tried on Wayland.

Why is your Qt 6 System Monitor trying to load a Qt 5 version of KNewStuff? That looks like a serious misconfiguration of either your system or your distribution.
Yes, that's clearly not going to work. :) There's some kind of local misconfiguration at play here.
