In the gameover rpc I can't understand this error and why it would be caused by this line this error is triggerd when the game ends and gameover rpc is called
I havent tried anything except trying to decypher the error.
Here is the playerScore class:
using System.Collections;
using System.Collections.Generic;

using Photon.Pun;
using System.Security.Cryptography;

{

stream.SendNext(score);
}
else if (stream.IsReading)
{
player = PhotonNetwork.CurrentRoom.GetPlayer((int)stream.ReceiveNext());
score = (int)stream.ReceiveNext();
}
}
