As an initial troubleshooting step, I suggest you to restart the computer and check if you are able to successfully change the lock screen wallpaper.

  From Desktop, right click and select
  Personalize.

  In Personalization window, click on
  Lock Screen in the left pane.
  
• 
  And choose wallpaper you would like to apply for the lock screen by choosing the browse option.

  Close the Personalization window.
