Network control panel of System Preferences, is "blank"

27" Retina iMac… macOS 10.13.1…

I just did a "fresh" re-install of macOS High Sierra, and my problem has persisted: the Network control panel of System Preferences, is "blank". This is despite my Mac having both WiFi and Ethernet connections active. Viewing the Network pane causes a spinning beachball. Force-Quit works, but I need to make changes in the Network configuration, and it does not appear. The only connected device is a backup USB HD.

What's going on? How can I fix it?

Please locate the developers instructions to uninstall CMM and uninstall. Mac OS does not need any cleaning, antivirus or any third party “maintenance “ apps installed.

After uninstalling CMM restart in Safe Mode and then restart normally and test.

Thanks for your persistence, den.thed. Going through each of those troubleshooting steps was a helpful reminder of the logical, ordered process of solving a problem like this.

Much obliged.
