Lockscreen picture wallpaper not correct

Describe the bug SetImageFileAsync API has a bug when being called from a non-UWP process: https://stackoverflow.com/questions/56935486/cached-image-not-being-updated-with-lockscreen-setimagefileasyncfile One possible solution/workaround would be to use background task: https://docs.microsoft.com/en-us/windows/uwp/launch-resume/support-your-app-with-background-tasks

To Reproduce Steps to reproduce the behavior:

1. Set lockscreen wallpaper, multiple times.
2. Check if wallpaper updated successfully.
3. Restart system, lockscreen will not have the recently set wallpaper but cycle between old ones.

Additional context Probably best to disable the setting till issue is resolved.
