Confirm that the USB camera device has not been recognized, and verify if other images are functioning properly or if all images are no longer recognized properly. If so, there may be hardware abnormalities.
When the machine is powered off, unplug the LCD cable again. The USB signal of the camera is connected to the LCD cable. -
@George tried and older image with kernel 5, and tried to unseat and clan the cable of the monitor with 99% alcohol, still no video device
