Hey BlitzDayTeam,
we have an asymmetric VR Game for two players and we want to make it multiplayer. However whenever we start the client on the MPPM window we get this exception.
But I can 100% confirm that the scene we are using is in the build settings.
Using unity: 6000.0.5f1 and MPPM 1.2.1 (same error also happend in 1.1.0 )
This code that seems to trigger it is: but it crasehd after 2.1 so it must be: while (!networkManager.IsConnectedClient)
StartCoroutine(WaitForConnection());
IEnumerator WaitForConnection()
{
Debug.Log("StartClient() + 2.1");
while (!networkManager.IsConnectedClient)
yield return null;
Debug.Log("StartClient() + 2.2");
ClientStarted?.Invoke(string.Empty);
Debug.Log("StartClient() + 2.3");
}
It also happens when the MPPM window is the host and the MainEditor window tryies to join as Client. However the error also appears only in the MPPM window not in the Main Editor.
Then the exception looks like this:

How can we resolve this? Because of this we had to switch to ParrelSync but we would prefer to use MPPM.
