For the last few days I've been getting a message on my lock screen
Unlocking with Apple Watch is not available with your screen is being shared

But I got it this morning after a full restart and without my secondary monitor attached. Now I'm kinda worried! Is my screen being shared with someone?! How would I even know?!
note that screen sharing is off:
