[ISSUE] Error fetching network interface list: NPE

[TotallyAvailable]

Describe the bug
After a regular Reboot the device came back as usual, connected fine... except the nearly completely broken Network connection.
Nothing network related has been touched in months. No System Update since the last successful reboot.

The previous wall of text disappeared just like the long list of issues it used to describe.

Additional context

(Guess in the meantime I'll have to find where the actual offending interface config is stored and how to get rid of it without breaking the last bit of functionality.)

Also please the option to hide disabled Apps as well.
