KDE ignores keyboard settings

[ralphb]

After rebooting Kubuntu 20.04, KDE suddenly ignores all my keyboard settings, including
- increased key repeat rate and decreased key wait time (in Input Devices/Keyboard/Hardware)
- mapping CapsLock to Control (in Input Devices/Keyboard/Advances)

These settings are displayed correctly in System Settings (see attachment), but don't work at all.

Interestingly, most of my custom key shortcuts still work.

Are there issues with System Settings, or is one of my configuration files damaged? Which file would I have to delete to reset keyword settings?

I did find file .config/kxkbrc:

[Layout]
DisplayNames=
LayoutList=de(nodeadkeys)
LayoutLoopCount=-1
Model=pc105
Options=caps:ctrl_modifier
ResetOldOptions=true
ShowFlag=false
ShowLabel=true
ShowLayoutIndicator=true
ShowSingle=false
SwitchMode=Global
Use=true

So why is CapsLock not Control?

I could not find a package starting with 'k' that would hint at input configuration, so I chose kubuntu-meta. Please select an appropriate package, I really don't know where this belongs.
