My HP Pavilion laptop has Ubuntu 18 version and I once tried to disable InBuilt webcam just for security reasons. But now it wasn't working and I reinstalled newer version of Ubuntu 20. But even after installing newer version the camera is still not working.

When I open cheese it shows this screen.enter image description here

I assumed I might have deleted the drivers as I was doing package installation and removel that time.

Please suggest me what should I do to get this working.
