How to fix - can't start your camera - error code 0xA00F429F - I have been in touch with MS and it may be a driver issue - the other error has shown that another app is using the camera

    Hi, let me help you.

    Have you tried a hard reset?

    Turn off the laptop.

    Unplug the charger.

    Remove all USB devices.

    If the battery is removable → remove the battery.

    Press and hold the Power button for 30–60 seconds.

    Reinsert the battery (if removed).

    Plug in the charger.

    Turn the laptop on.
