So ,,, I had/have a similar problem ,,,,last Saturday after a round of updates I rebooted to a black login with just a cursor .

going to a TTY and using "startx"or "startkde" just got me back to the black screen .

from the TTY I upgraded the Nvidia driver ,,,,no good ,,,then did a "mv" on .config .local and .kde to .local.old and so forth .
then the "startx" worked and got me back to login screen and loged in .

in my haste to try to get all my settings back I again did the "mv" thing BUT forgot to "mv" the new defaults to something else first ,,,so when I did "mv .kde.old .kde" instead of getting back my old .kde ,,,,it was gone .

as of now I can reboot and login as normal and all the programs I have tried so far are working as expected ,,except "system settings" ,,,I can do nothing with system settings>workspace theme>look and feel or desktop theme (the get new themes button is not even their),,,and trying to add program to autostart crashes system settings.

<GROAN>... I wish it had been on one of the BTRFS partitions where I do use @oshunluvr's snapshot service menu for dolphin to make snapshots of the systems installed (Neon-lts & Kubuntu-17.10)

the only errors I could find in loges when it happened was the same one your talking about ,,,,,so why I am posting my tragedy ,,, I was hoping some update mite fix things but not yet .

I think that is what will happen, eventually. In my case all I have to do is be patient for 15 seconds and it will heal itself.
But, the next time it happens I am going to pay careful attention to what is running and try to identify the app this is running with the wrong version number.

so I got tired of waiting for a fix to come down the pipes and started to investigate this further ,,,,,,gosh I am laze this was kinda easy .

first launch "systemsettings5" in a konsole and click workspace theme then desktop theme

Code:

vinny@vinny-Bonobo-Extreme:~$ systemsettings5
KActivities: Database connection:  "kactivities_db_resources_140334613874944_readonly" 
  query_only:          QVariant(qlonglong, 1)

  wal_autocheckpoint:  QVariant(qlonglong, 100) 
  synchronous:         QVariant(qlonglong, 0)

^C

see the parts in red,,,,,,,,,,,, then "locate kcm_desktoptheme"

Code:

vinny@vinny-Bonobo-Extreme:~$ locate kcm_desktoptheme
/usr/lib/x86_64-linux-gnu/qt5/plugins/[COLOR=#ff0000]kcms[/COLOR]/kcm_desktoptheme.so

Aha ,,,,,,,,look in ,,,,,,,/usr/lib/x86_64-linux-gnu/qt5/plugins/kcms/,,,,,,,,

Code:

vinny@vinny-Bonobo-Extreme:/usr/lib/x86_64-linux-gnu/qt5/plugins/kcms$ ls
kcm_desktoptheme.so  kcm_energyinfo.so  kcm_fileindexermonitor.so  kcm_lookandfeel.so  kcm_plymouth.so  kcm_pulseaudio.so  kcm_splashscreen.so

well thats why a lot of things wernt working

,,,krusader to the rescue ,,,,,,,,,,,copy all the stuff in /usr/lib/x86_64-linux-gnu/qt5/plugins/kcms/ to /usr/lib/x86_64-linux-gnu/qt5/plugins/

Oops still no good

Code:

vinny@vinny-Bonobo-Extreme:~$ systemsettings5
KActivities: Database connection:  "kactivities_db_resources_140280649029888_readonly" 
  query_only:          QVariant(qlonglong, 1)

But half the errors are gone

"apt search org.kde.kcm" gives ,,,,,,,,,,,,,

vinny@vinny-Bonobo-Extreme:~$ apt search org.kde.kcm

Played with your solution.
Did the copying part. That gave me:

Code:

$ systemsettings5     
Trying to use rootObject before initialization is completed, whilst using setInitializationDelayed. Forcing completion

but the app you installed isn't in my repository.

**vinnywright** · Dec 12, 2017, 04:19 PM

this is what I am getting now starting system settings and clicking "workspace theme" (look and feel by default),,,,,,,,,
