Gnome-control-center won't open except under sudo

[Mr_Magoo]

As the title says, the gnome-control-center won't open from Zorin menu > Settings, nor from the icon corral at the right-hand side of the taskbar.

If I open Terminal and enter sudo gnome-control-center, it opens just fine, but it's got the settings for sudo, not for my username.

If I open Terminal and enter gnome-control-center, I get:

** (gnome-control-center:15950): WARNING **: 21:48:14.840: Ignoring broken panel info-overview (missing desktop file)

** (gnome-control-center:15950): WARNING **: 21:48:14.851: Ignoring broken panel wacom (missing desktop file)

Bail out! ERROR:../shell/cc-shell-model.c:419:cc_shell_model_set_panel_visibility: assertion failed: (valid)
Aborted

Methinks I've stripped out a bit too much. Any ideas to get it working again?

I've already tried: sudo apt reinstall gnome-control-center

Got it fixed. It apparently wasn't anything I've removed (since I've not removed anything in quite awhile), it was apparently a glitch in the data being stored.

Here's how to fix it:
sudo rm -r .local .cache
