Last boot, I updated https://github.com/luisbocanegra/plasma-smart-video-wallpaper-reborn, acquired via plasma-discover-6.5.5-1.fc43.x86_64. Upon successful `qdbus-qt6 org.kde.LogoutPrompt /LogoutPrompt promptReboot`, when SDDM was automatically bypassed, as I've configured its KCM to do, I observed that PlasmaShell was not visible. Invoking it via BaSH didn't remediate this. To demonstrate, `time strace -Ttr qdbus-qt6 org.kde.plasmashell /PlasmaShell org.kde.PlasmaShell.activateLauncherMenu` fails, and returns:

Consequently, I attempted to change wallapers, via the relevant KCM. However, doing so reproducibly causes this ANR.

(In reply to Mr. Beedell, Roke Julian Lockhart (RJLB) from comment #13)

I have reported this, upstream, at https://bugs.kde.org/show_bug.cgi?id=516065#c0.

Reproduction instructions:
Open system settings
Navigate to Keyboard -> Shortcuts
Searach for "desktop"
Delete "desktop"
Type "display" -> triggers crash when attempting to type  the "p" in "display"

This isn't limited to these specific queries, but I can't easily identify what exactly causes it. I can usually get it to trigger on the second search attempt, but not always
