settings error

SUMMARY
Clicking on some settings in the side panel shows an error message that can only be fixed by a reboot. I discovered this accidentally when I was trying to set the firewall in the settings and got this error

This one is when I open firewall settings

STEPS TO REPRODUCE
There is no specific pattern or a certain thing that I have to do reproduce this bug, as it just happens randomly without a certain pattern. I just open the settings and try to change somethings by clicking on the side panel and then get this error on some parts of the settings. And it seems to be just a random part of the settings (AFAIK)

OBSERVED RESULT
Error loadings some settings in the side bar of the settings app

EXPECTED RESULT
No errors in the settings
