No problem, we all have more important things to do at times.

That "GreeterEnvironment=" in your  sddm.conf  looks suspect to me.  It
has to be a comma-separated list but you have newlines in it.  It will
set the variable to a different value than intended.  You could check
this with
    echo "$GreeterEnvironment"

So I suggest to either leave the variable at its default (unset) or if
you think you really need it, remove the newlines or try line
continuation (\) to make it more readable:

GreeterEnvironment=QML2_IMPORT_PATH=/opt/kf6/lib/qml:/opt/qt6/qml,\
QT_PLUGIN_PATH=/opt/kf6/lib/plugins:/opt/kf6/lib/plugins/kcms:/usr/lib/plugins:/opt/qt6/plugins,\
XDG_DATA_DIRS=/usr/local/share:/usr/share:/opt/kf6/share,\
XDG_CONFIG_DIRS=/home/dave/.config/kdedefaults:/etc/xdg:/opt/kf6/etc/xdg,\
PATH=/usr/local/bin:/usr/bin:/opt/kf6/bin:/opt/qt6/bin

Can't make anything of this.  Have you tried google with
"kf.dbusaddons: Skipping syncing of environment variable"?

Perhaps it's a side effect of that wrongly set GreeterEnvironment?
