Build error [Failed to load: Can't find file]

I can run the game in the editor, i’m using playfab blueprint plugin and i can login and start the game.

When i try to build i get a lot of errors that seems related to files concerning Playfab not being found. like this:

UATHelper: Packaging (Windows (64-bit)): Cook: LogLinker: Warning: Can't find file '/Script/PlayFab'

UATHelper: Packaging (Windows (64-bit)): Cook: LogProperty: Error: UStructProperty::Serialize Loading: Property 'StructProperty /Game/Game/Blueprints/Base_GameState.Base_GameState_C:OnRegistered.result'. Unknown structure.

Any idea how i could fix this ?
