Comment 2 Luca Beltrame 2022-02-18 21:55:00 UTC 
systemsettings is not the only affected application. In my setup, plasmashell crashes at startup with a similar backtrace. 

Reverting 0943bbf5 in kdeclarative fixes the crash.

There was a fix in the latest version. If you are using git version of frameworks, you need to update and recompile it.
