Unsolicited Webcam feed in Rhino?

This started happening yesterday and is freaking me out.
An icon of a (laggy) live feed from my webcam is appearing within Rhino, at the bottom right corner of my view port + any window that pops up (ex. Block Editor, Preferences).
I haven’t downloaded any plug-ins recently.
Any idea where this came from and how to make it go away?
Thank you so much! !
