unable to unblock developer in security & privacy preferences pane
In my security and privacy preferences, I have a "The developer 'Google, Inc.' is currently blocked". When I unlock preferences, and then click on "Accept" nothing happens.
In console, I see this particular event strongly correlated to the mouse click for that button:
com.apple.preference.security.remoteservice Dropping mouse down event because sender's PID (112) isn't 0 or self (423)
At present, this is blocking Google's Drive File Stream.app for working correctly.
How do I get macOS to accept this developer? FWIW, I have Chrome.app running without issue.
Note: using macOS 10.13.3
iMac, macOS High Sierra (10.13.3)
