XPS 13 - Windows 11 Webcam fails to start or be recognised

A few weeks ago the webcam just stopped responding and all my teams call switched to audio only.

I have run support assist and the camera does not show up as a piece of available hardware to troubleshoot. It is enabled in the BIOS and has no errors currently showing in device manager. It is listed as Intel(R) ADL AVStream Camera.

I have tried all available versions of this driver, all were unsuccessful.

I have today performed a factory reset and run all available updates and still no joy.

Is this a known issue on windows 11?
