In July 2019 I purchased this computer and have loved it.  With COVID-19 and the fallout that has occurred as a result, I finally had to use my webcam -- and it does not work.  I have looked in the BIOS and the webcam is enabeld.  All software has been updated.  However, when I look at the Device Manager in Windows 10 under Cameras, the Integrated Camera is identified as disabled (Code 22).  Enabling the device does not work.  The driver is a default Microsoft, version 10.0.18362.693.  Updating the driver has not been successful (Win10 reports "the best drivers for your device are already installed.").

Attempting to use Microsoft Camera indicates "We can't find your camera," which makes sense but wanted to check regardless.  it suggests that my antivirus software could be blocking the webcam but if that is the case I cannot find where in the software it could be blocked.  I'm using Norton 360.  I have an external camera on my desktop (built that one myself) and have no problems.  I also have an Dell Inspiron 5477 with a built-in camera that works just fine.  All three cameras are using Norton 360; this does not feel like it is likely to be the cause of this problem.

Looking at Dell, there does not appear to be a driver for the webcam that can be identified.  I am out of ideas.  What have I missed? 

Thank you,
