With the current social distancing protocols in place many of us have to start using our integrated webcams. DELL, please fix this error message, "0xA00f4244 no camera available". When I try to use mine I receive the error message that my camera cannot be found.  Please see the below attempts and come up with a patch to fix this:  1 my antivirus is off not causing the problem  2 camera does not show in device manager. repeat there it is clear how to reinstall drivers if camera is not showing in device manager. scan for hardware changes does nothing  3 USB root kit deletion does not work  4. the driver for this is nowhere to be found. I did go ahead and update my windows and BIOS drivers  5. the privacy settings changing the slide tab to allow does not work  6. The reset in the windows app store does not work or the troubleshooter  Who is the camera manufacturer? How will I ever know? Please try to solve this problem.
