Updated to KDE Plasma 6.7 and now my display config window doesn’t work. It displays the error “No KScreen backend found. Please check your KScreen installation.”
I did some googling, and ran kscreen-doctor --info, which gave me the following -

Environment: 
  * KSCREEN_BACKEND           : [not set]
  * KSCREEN_BACKEND_INPROCESS : [not set]
  * KSCREEN_LOGGING           : [not set]
Logging to                : [logging disabled]
Preferred KScreen backend : KSC_XRandR.so
Available KScreen backends:
  * KSC_Fake.so: /usr/lib64/qt6/plugins/kf6/kscreen/KSC_Fake.so
  * KSC_KWayland.so: /usr/lib64/qt6/plugins/kf6/kscreen/KSC_KWayland.so
  * KSC_XRandR.so: /usr/lib64/qt6/plugins/kf6/kscreen/KSC_XRandR.so

I don’t know where to go now! Any help?

Figured it out. plasmazones was holding back kwin. Removed plasmazones, upgraded using Discover, reboot, everything works.

This was also causing other problems like crashing when switching desktops using the Pager widget, and various missing settings in other KCMs.

I’m surprised it wasn’t more broken than it was.
