Delete all files in C:\Users\User_name\AppData\Local\Packages \Microsoft.WindowsStore_8wekyb3d8bbwe\LocalCache, and then reboot your pc.
Edit: it will rescan all your downloaded files in just a few minutes then will let you launch the game.
If this doesn't work for you then you must have an issue elsewhere. Please let me know if this works for you. Fair winds~
