App craches using facebookSDK with VideoSplashKit

[JeanVinge]

I Don't know why but my app is crashing because of this line of code,

        self.moviePlayer.player?.addObserver(
          self,
          forKeyPath: "status",
          options: .New,
          context: nil)

observation: when commenting this line of code, i solve the error

the problem is, i have a button that make the login with facebook, and the video in the background, using VideoSplashKit, when i make the login with facebook, we go to the facebook webview, and when going back to the app i get this error:
