Fail: Extract cache file & apply wallpaper

I try to apply a wallpaper from a cached image, the whole process goes smoothly, but it doesn’t apply.
I can physically see the image in the new directory.

Share AIA so the community people can easily test and check whether issue with AIA or App

Please help!! all day with this inconvenience with no apparent solution.
There is something that I cannot understand, in this process it works perfectly, with and without connection, I transfer it to another project and it does not apply the background, although the physical file exists.

I use the same process previously to load the images in a viewer and they load offline from the cache, but when I try the same and apply to the wallpaper it does not apply
