Dear Maintainer,
after last upgrades, the quicksettings button to toggle virtual keyboard
doesn't work anymore. Regardless of pressing it, the button remains
enabled. System is Mobian testing on op6-enchilada.

Workaroud is to open plasma-settings and disable virtual keyboard from
there.

I wasn't able to reproduce the issue in up-to-date pmOS, then this seems
Debian-specific.

I've noticed the following lines in the journal:

ago 14 23:53:47 mobian kwin_wayland_wrapper[2958]: qt.qpa.wayland:
qtvirtualkeyboard currently is not supported at client-side, use
QT_IM_MODULES=qtvirtualkeyboard at compositor-side.
ago 14 23:53:58 mobian kwin_wayland_wrapper[2958]:
qt.virtualkeyboard.hunspell: Hunspell dictionary is missing for "it_IT".
Search paths QList("/usr/share/qt6/qtvirtualkeyboard/hunspell",
"/usr/share/hunspell", "/usr/share/myspell/dicts")
ago 15 22:52:50 mobian plasmashell[3063]: Executing
"plasma-open-settings kcm_mobile_onscreenkeyboard"
ago 15 22:52:52 mobian plasma-settings[26008]: unable to find module
"kcm_mobile_onscreenkeyboard"

but these are seen in pmOS as well, then likely not the root cause.
The following isn't found in pmOS log and therefore likely the root cause:

ago 14 23:53:53 mobian plasmashell[3063]:
file:///usr/share/plasma/quicksettings/org.kde.plasma.quicksetting.keyboardtoggle/contents/ui/main.qml:16:5:
Unable to assign [undefined] to bool

that refers to [1] where the "enabled" status for the quicksettings
button is defined, that fits with the symptoms. AFAICT looking at the
code, this relies on plasma-workspace and kwin, but I've no idea how to
check in which Debian package the issue lies.

Kind regards
Marco

After today's upgrade (including kwin and plasma-mobile), the button
works again.
