Windows Spotlight no longer working on Lock Screen

Hi there,

This is a recurring issue that I used to be able to fix.

I have tried every hack available online. Toggled on and off, cleared cache files, reregistered in Powershell, fix via command prompt, checked for Windows updates and restarted computer a thousand times. Spotlight works perfectly on the background, but NOT on the lock screen. It defaults to the blue flower thingy.
