Windows 10: Ctl Alt Delete to unlock PC loops back to Ctl Alt Delete to unlock PC

This is on a freshly imaged laptop running Windows 10 Pro version 10.0.18362. I also had this same problem before imaging the laptop.

I'll leave my laptop locked for the night and when I try to login in the morning, I can't. Every time I press ctl+alt+delete to bring up the password prompt, the screen starts to change like it's bringing the prompt up but then immediately flashes back to the "Press ctl+alt+delete to unlock" screen. The only way to actually log in is to hard power cycle the laptop. Then I can log in.

I took a look the Application Event Viewer, and there are hundreds of identical errors, starting from when I locked my PC last night to when I hard rebooted the laptop. All of the errors are:

"System Center failed to validate caller with error DC040780"
Log Name: Application
Source: SecurityCenter
Event ID: 17
Level: Error
User: N/A
