desktop functionality is just gone after update

English Applications
#1

after updating today all that was left of my desktop icons was this:

Error loading QML-File: file:///usr/share/plasma/plasmoids/org.kde.desktopcontainment/contents/ui/main.qml:36:1: Type FolderViewDropArea unavailable
file:///usr/share/plasma/plasmoids/org.kde.desktopcontainment/contents/ui/FolderViewDropArea.qml:1:1: Expected token `numeric literal’
file:///usr/share/plasma/plasmoids/org.kde.desktopcontainment/contents/ui/FolderViewDropArea.qml:1:1: Expected a qualified name id

Things I’ve tried to fix this: zypper dup, zypper up, creating a new user (same thing happens), changing desktop settings (no effect)

Any suggestions?

Could you show output ( between CODE tags) of

zypper lr -d
