Hello Wamdon,
In order to diagnose your issue, I’ll need some more information from you. What platform are you packaging to, and which device are you planning to use? Could you provide the steps that you are using to package your game? Also, be sure to have a look at the packaging and cooking documentation to see if you can find information regarding the issue that you are having: Packaging and Cooking Games | Unreal Engine Documentation
Have a great day,
Sean Flint
