My organization has been having an issue for a few months now where a user will try to unlock their Windows 10 computer but no field populates to enter their password. Sometimes the username will appear, other times nothing will appear. On the lock screen you can see the date and time, but once you hit enter, it goes blank (you can still see the lock screen wallpaper). A simple restart will fix this, however at the rate this is happening that is only a work around, and if the user has an unsaved document that presents a problem. The troubleshooting steps I’ve tried based on my own research have been to disable Fast Start under Power settings and to make a registry edit which disables the lock screen. Disabling Fast Start had no effect and disabling the lock screen seems to at best lessened the frequency of the issue occurring to once every two or three weeks.
