Did you reboot after the update?
Can you update again? Looks like plasma-desktop was updated but plasma-workspace wasn't yet, transient breakage due to the nature of using git builds :)
The plasma-workspace build [1] is currently broken and has a commit [2] which a change in plasma-desktop depends on. [1] https://build.neon.kde.org/job/bionic_unstable_kde_plasma-workspace/ [2] https://cgit.kde.org/plasma-workspace.git/commit/?id=5e1b650859fe5287f25f3a2306a6ac26058c46c6
All fixed now.
