How can I discover the exact path to the “Lock Screen”>”Background”>”Slideshow” folder Windows 10 is using?

I created a folder named “Lock Screen” to use as the album for my Windows 10 “Lock Screen”>”Background” slideshow. However after a recent Windows update (currently on Windows 10.0.19045 Build 19045), the slideshow switched to some other unknown album – but it’s still showing “Lock Screen” as the folder it’s using. The pictures showing in the slideshow aren’t in the “Lock Screen” folder that it is displaying as the album it’s using for the “Lock Screen”>”Background” slideshow.

Ideally, I’d like to know how to fix this problem. I’ve tried all the troubleshooting techniques I could find on Microsoft Support and GPT-4. None worked.

Alternatively, I’d like to get the path to whatever folder Windows is actually using for the slideshow and just move the pictures I want to use into that folder.

Any help appreciated!
