macOS Mojave - System Preference, Security & Privacy, Accessibility - Not Working/Empty

Hi,

This is quite a copy paste of a previous question in this forum - System Preference, Security & Privacy, Accessibility - Not Working/Empty

However, the solutions offered did not solve the problem on the new Mojave version and therefore I'm asking again.

Just updated to the latest Mojave 10.14 (18A391).

After the update my System Preference, Security & Privacy, Accessibility access list is not working, it's completely empty/blank and I can't use +/- either. They do nothing. The + does try to add an app and I can select an app via the dialog box but the window just still shows blank after choosing an app. It never adds anything.

I have rebooting numerous times and power-cycled also to no avail. I have also used Onyx to repair Permissions and also CleanMyMac utility, all passed perfectly fine.

The list never used to be empty, there were several apps listed in there such as DropBox and BetterTouchTool, but they're all gone now. It's completely empty.

I'm having major issues because apps that were once on the list now won't run till I add them to the list, but I can't. I would even purchase another app that could control this list, but I don't know of any app that does.

I hope someone has a solution or an idea of what to do because you've experienced the exact same situation.

Thanks in advance,

Alex
