2. Disconnect USB camera.
3. Lock screen.
4. Press Hello Face sign-in on lock screen.

I thought you commented the wrong issue)
After i enable the built-in camera with the app options - there's no such an issue any more.

What is the status of built-in camera after 1 and 2 but before 3?
What happens if you click "Re-check USB camera" after 4?

I'm disabling built-in camera with the app options and it's disabled before 2 and 3, and the USB one is enabled, after pressing recheck USB - the USB one is still enabled and works, but the built-in is disabled. After 4 i'm seeing messages on lock screen: "Getting ready" first and then "Couldn't turn on the camera".

Your explanation is contradictory. After 2 (USB camera is disconnected), the USB camera cannot be enabled. What is the exact status of built-in camera after 2?
And could you run this app from command line with "/operation"? It will create operation.log at "C:\ProgramData\HelloSwitcher" folder. Could you post it?

Sorry, yeah, after 2 the built-in is still disabled - which is the purpose of this issue)
Strange, but after system restart i can't right now reproduce the issue, Here are my operations files - 1 is with disabling/enabling the build-in (either HD or IR) camera and 2 is enabling/disabling HD and IR cameras as i have two devices in device manager, but they're a single camera device in my laptop.
1 - operation.log
2 - operation.log
