An expired security certificate made all Surface X cameras to stop working
A flood of Surface Pro X owners took to Reddit yesterday to complain that their webcams unexpectedly stopped working — an issue that can have various repercussions.

Surface Pro X owners attempting to use the camera are greeted with the following error message:​
Error code 0xA00F4271<MediaCaptureFailedEvent> (0x80004005).

What's interesting about this particular issue is that it affects every single Surface Pro X customer. Given the encompassing nature of the camera failures, the most likely culprit is an expired security certificate, according to Reddit user Wapitiii.

If you roll your Surface Pro X back to any date before May 23, 2023, the camera "magically" starts working again — giving credence to the suggestion that a security certificate is to blame.

This isn't a good workaround, by the way, as rolling back the date on your device can result in authentication problems for secure websites or programs on your PC.
Microsoft earlier today released the Windows 11 "Moment 3" Update (KB5026446), but it is doubtful that it addresses the camera issues faced by Surface Pro X owners.
