I just updated this morning - and latte was dead… the update complained about a fair few /latte folders, so I had to delete a ton of them before installing it, thankfully not the config folder and it’s back to normal.
Give it a go - close Latte, then clean up and re-install and see if it helps:
doas rm -R /usr/share/plasma/shells/org.kde.latte*
doas rm -R /usr/lib/qt/qml/org/kde/latte/*
doas rm -R /usr/share/plasma/plasmoids/org.kde.latte.*
The problem appears to have gone away on its own.
I might have inadvertently changed a setting, or a recent build fixed the issue.
Either way, this can now be marked as solved.
