Your PlayFabMultiplayerManager calls DontDestroyOnLoad on its initalization. This can cause issues in some architectures. We do not use nor allow use of DontDestroyOnLoad in any of our games so we have to edit your script to fix this.
If you want to provide this feature for people fine but make it a public bool people can turn on and off via the inspector (many assets do this including Mirror) so they dont have to edit your SDK scripts to remove an unwanted feature.
