Surface pro 7 login says "Couldn't turn on the camera, please sign in with your pin"

Yes, this did work and noticed that only the IR camera came on.  Normally, my work-round to the problem when Hello does not activate is to initiate 'Restart' option which activates both front cameras and from the on all is OK except that more often than not, the ARC Blue Tooth mouse is slow to activate and requires some manual prompting via 'Settings.'   I find that once Hello has been activated, via this process, it works OK for consecutive sessions.

This worked for an hour, then the camera stops working (the lights above the screen are on). Lile something else is using the camerabut there is nothing in task manager that says it is. As above, camera works after restarting (for an hour)

So still need a fix as i can't reatart the computer every hour to fix the camera

I have the same issue, I did system upgrade, stopped the camera and enabled again from device manager seems working fine (for an hour so far)

This worked so well thank you so much.

Does it worry anyone else that the camera light is on, which I assume means the camera is in use, and we have no idea what app is using it, and who might be watching?

I'm not usually paranoid about this stuff, but makes this makes me uncomfortable. Seems like a major privacy concern caused by a bug in Microsoft Software?
