Hi DoubleG1, try to go to device manager > look for system devices > Can you please confirm if you have "Intel Control Logic"? If you do, right-click on it, click uninstall then check the box that says "Delete the driver software for the device" > Then restart the device.
this solved my problem.
I have a Surface Laptop 2 and have been doing some driver updates using a third party driver updater. it seems that the newest Intel Control Logic driver (version 60.19041.1.3035 from 16 sept. 2020) that was pulled has some issues with the Microsoft Camera Front and Microsoft IR Camera Front devices.
I just removed the two instances of the Intel Control Logic, ticking the ”remove driver” box and restarted the computer. the camera and IR sensor now work and the Intel Control Logic driver reverted to version 30.15063.6.8611 from 3 dec. 2018. all good now; not gonna update again those drivers
