Huh?? that weird... maybe the file got corrupted so try download again. Also if you mean doesn't work on Android try download file manager name Solid Explorer or ZArchiver.
The issue is that you didn't assign a platform when uploading so the files in the Itch app look just like Files and not a valid game install for "X" platform. If you assign the files as valid for Windows for example players on the windows Itch app will be able to download it.
