SUMMARY


STEPS TO REPRODUCE
1. Install a SDDM theme;

OBSERVED RESULT
System Settings doesn't open anymore unless systemsettings5 process is ended in KSysGuard.

EXPECTED RESULT


SOFTWARE/OS VERSIONS
Operating System: Kubuntu 21.04
KDE Plasma Version: 5.21.4
KDE Frameworks Version: 5.80.0

ADDITIONAL INFORMATION
This problem also happens when installing icon packs from the repositories such as pocillo-icon-theme and papirus-icon-theme. I don't know if this is related.

Can confirm, yikes.
Comment 2 Nicolas Fella 2021-05-03 20:43:47 UTC
My guess is that there is a running KJob somewhere that prevents the app from closing completely
Comment 3 Lua 2021-05-18 00:28:49 UTC
I just had this bug when installing an iconpack package via terminal. After killing the systemsettings5 process, I was able to relaunch System Settings with no problems.
