If you open the Camera app, what does it say? Any error message? Or is it just a black screen? Any additional information would be helpful if you don't mind.
Most camera issues can be due to a physical privacy cover covering the lens. Make sure that's not the case.
Otherwise there is usually a physical button/key/switch you can use to turn the camera on or off. For example, most Lenovo uses F8 or Fn+F8, or a switch above the lens, HP has a camera key or a button on the side of the laptop, MSI uses F6 or Fn+F6, etc.
If you are not sure, tell me what the camera app says/shows, and then please hold down Windows + R keys, type in msinfo32.exe and hit enter. Then share a screenshot of the System Information window. Thanks!

Try these steps in order:
If the camera is missing in Device Manager, use Action > Scan for hardware changes. If it still does not appear, manufacturer support may be needed.
