Short summary:
Googled around for the error and found
https://bbs.archlinux.org/viewtopic.php?id=222486 suggesting
export QML_DISABLE_DISK_CACHE=1
then running
systemsettings5
This works, but you have to know to use that environment variable everytime you
want to change settings, and to run systemsettings5 from a command line.
I couldnt find a duplicate bug for this. I apologize in advance if this is a
duplicate and I could not find it.
