Hi,
It sounds like Windows thinks your webcam has been turned off by a hardware control, which is why you’re seeing that blocked message. Many laptops have either a tiny physical slider near the camera or a function key (often F8, F10, or one with a little camera icon) that can toggle it on and off, so it’s worth giving those a quick check. If that’s not it, the next place to look is Windows privacy settings to make sure apps are actually allowed to use the camera. In short, it’s either the laptop itself telling Windows "camera disabled" through a key or switch, or Windows is blocking access at the software level checking both should usually pinpoint the culprit.
Kind regards,
