I'm trying to package my game for a friend to test but it keeps failing.

Seems like there’s an issue with a plugin i’m using. I’ve packaged the game with the plugin and haven’t changed anything related to it since then so idk what’s happening.

Hi Dedlus, the issue that I can see from this UE_LOG is basically Expecting to find a type to be declared in a module rules named ‘KawaiiPhysics’ in UE5Rules which means it is expecting KawaiiPhysics to be declared in Unreal5Rules . So you either disable this module and then try to package again or you can add it to UE5Rules.
