set wallpaper action is not working on windows

<img width="1904" height="1095" alt="Image" src="https://github.com/user-attachments/assets/e14b25de-af1e-44e8-8fec-ab8559b31c3c" />

I added a custom shortcut key for setting the wallpaper, but even though I saved the shortcut, nothing happens when I press it.
