To find out if it's system wide or user specific, try this...

Open System Preferences>Users & Groups, unlock the lock, click on the little plus icon, make a new admin account, log out & into the new account.

Does it work in the new account?

See if you have unknown Profiles.

To remove a configuration profile in macOS:

From the Apple menu, select System Preferences....
From the View menu in System Preferences, select Profiles.Note:
Profiles won't be visible until you have at least one profile installed.
Select the profile you want to remove, and then press the - (minus) button. Click Remove to remove the profile.
