Question

My game doesn't load on my phone and in my console, So many errors pops up but the build is successful?

Here is most important errors:

and it might be linked to my saving manager:

using UnityEngine;
using System.IO;
using System.Runtime.Serialization.Formatters.Binary;

public static class SaveManager 
{

    public static void SavePlayer(PlayerMovement player)
    {
        BinaryFormatter formatter = new BinaryFormatter();
        
        string path = Application.persistentDataPath + "/player.T2T";
        FileStream stream = new FileStream(path, FileMode.Create);

        GameData gameData = new GameData(player);
        
        formatter.Serialize(stream, gameData);
        stream.Close();
    }

    public static GameData LoadPlayer()
    {
        string path = Application.persistentDataPath + "/player.T2T";
        if (File.Exists(path))
        {
            BinaryFormatter formatter = new BinaryFormatter();
            FileStream stream = new FileStream(path, FileMode.Open);

            GameData gameData = formatter.Deserialize(stream) as GameData;
            stream.Close();

            return gameData;

        }
        else
        {
            Debug.LogError("Save file not Found in " + path);
            return null;
        }
    }
    
}
