Hello, In the plasmashell log I see a lot of Nullpointer error messages: plasma-desktop-6.3.0/share/plasma/plasmoids/org.kde.plasma.taskmanager/contents/ui/Task.qml:79: TypeError: Cannot read property 'status' of null So in line 79 of the file Task.qml of plasma/plasmoids/org.kde.plasma.taskmanager/contents/ui the code tries to read a 'status' property of something that is null. Looking in this file I see line 79 is the following: active: !inPopup && !tasksRoot.groupDialog && contextMenu.status !== PlasmaExtras.Menu.Open It is trying to read status from contextMenu. So contextMenu musst be null. I think in line 79 one there should be an extra null check before the 'status' property is accessed.
Introduced by me in https://invent.kde.org/plasma/plasma-desktop/-/commit/3b6d394c0f3336b6ab81a3dc0d770a4c08a0ed4b, and already fixed by Christoph Wolk in https://invent.kde.org/plasma/plasma-desktop/-/commit/f463cdfcfc2cc474b695b5629450dd96a4170039 for Plasma 6.4. Until then, it's harmless and you can ignore it, but I'll look into backporting it anyway.

You already did in https://invent.kde.org/plasma/plasma-desktop/-/commit/0ed639e4f99ecfb4e3f46512f205f123ba71b244; it barely missed the 6.3.0 window, so already fixed in 6.3.1. *** This bug has been marked as a duplicate of bug 500227 ***
So I did!
