I don't think I compiled anything directly. I do have some packages installed with yay, so I did a yay -Syu (and had forgotten to do so in some time) but that didn't change the problem.
I tried with a new user account too:

And it seems up to date.
It's weird my KDE just self destructed. I'm not sure if that error message indicates the systemsettings plugin is really the issue or not
