I have a small screen with camera image appearing in the bottom right corner of my monitor`s on my computer, and I can't remove it or interact with it. This screen isn't associated with any specific application, and I can't determine what's causing it to appear. I've closed all the applications that could potentially use the camera, restarted the computer, and checked the Task Manager, but I couldn't find anything that would explain this behavior. How can I resolve this issue?
