Hi,
If possible, do you have any third-party antivirus software? If so, which one?
If it's a laptop, what is the laptop model?
Access msinfo32.exe in the search bar, take a screenshot, and post it here.
Access the device manager, take a screenshot, and post it here.
Check the keyboard between the F1 and F12 keys to see if there's one with a camera icon. Press it to see if it unlocks. If that doesn't work, try Fn+F and the key with the camera icon.
Also check if it's a laptop; there should be a privacy palette located on top of the camera.
Thanks
