iPhone X Face ID not working suddenly

[billcao]

Using iPhone X with 11.3(15E5189f)
Sometimes Face ID suddenly stops working. It will go through a really quick authenticating process (about .5sec) and then it fails. Afterwards, when I hit cancel and try again, it will say "Face ID needs your password to be enabled". I have to restart my iPhone X every time when this happens and will go back normal.
Has anyone got the same problem?

Have you tried re-registering your face?

I would try deleting and re-registering your face. It may also be a bug since you're running the iOS 11.3 beta.
