AVG driver updater detects Cameral Sensor error that Dell & MS cannot

New Dell XPS, Windows 11. Built-in Intel camera device.
Camera worked a couple of days and then error message 'web camera cannot be detected;.
AVG driver update noted ‘Issue with HM1092 Camera Sensor’
After 8 hours of phone and online support from MS and Dell, neither one can detect this error and no one can get the camera operating.
How did AVG find this issue? Do you also have a solution?
