Lenovo IdeaPad S340 Integrated Camera not working

I have a Lenovo IdeaPad S340.  The integrated camera worked fine until I tried to do a virtual background with Zoom.  Now the camera only turns on an off and doesn't give a picture.  I have tried to turn on the camera from the settings and the function key, adjust the privacy mode from Lenovo Advantage, and uninstall the camera.  I end up with the same problem on of the camera turning on and off with no picture.  Any ideas about how to fix it?
