I had used an Intel RealSense F200 depth camera for Windows Hello Face Recognition.
It works fine under Windows 10 1809 and before.
After I upgrade my Windows 10 to Windows 10 1809 (18362.30), Windows Hello Face Recognition not work anymore.
It looks that the service of Intel RealSense "RealSenseDCM" can't start successfully.
There is error event 7023 of "Service Control Manager" in event viewer.
If try to start the service manually, it will show an error dialog with error code 0x80010119.
The error message in English is "Security must be initialized before any interfaces are marshalled or unmarshalled. It cannot be changed once initialized".
I had tested on another Windows 10 1903 PC, and have the same issue.
How can I fix it?
