Why sign in screen show a solid color?

If you haven't already, you could see if changing the lock screen image may refresh it to show on the sign-in screen.

As for the Windows Spotlight, you could see if resetting and re-registering it below may fix it.

You could try resetting Windows Spotlight on the other PC to see if it may sort it.
