Engine Bug for package

Hi,
We are trying to create Provision for our project. And we follow every step in this link: Setting Up an Unreal Engine Project for iOS | Unreal Engine 5.1 Documentation
But when we go to step6, and import our provision. The command line shows error says that “can’t find ‘…/4.7/engine/build/IOS/UE4Game-info.plist’”. And we can’t successfully import the “provision” file.
our system is windows 8.1.
