问题解答

存值时可以直接用变量名赋值，你当前写的存值代码完全符合要求，不是存值方式导致的加载失败。
加载后变量为空的核心原因：你仅完成了存档文件到stateVariables对象的反序列化操作，没有把stateVariables中存储的属性值同步回业务逻辑使用的静态变量。和你已经实现的装备、药水、经验变量赋值逻辑一致，其他游戏数值相关的静态变量也需要手动从stateVariables中读取赋值。

修正后的加载代码示例

string folder = Environment.GetFolderPath(Environment.SpecialFolder.MyDocuments);
folder = Path.Combine(folder, "RNGgameSaveFiles");
Directory.CreateDirectory(folder);
string dataFile = Path.Combine(folder, "RNGgameSaveFileV1");
if (File.Exists(dataFile))
{
    using (Stream stateStream = File.OpenRead(dataFile))
    {
        BinaryFormatter deserializer = new BinaryFormatter();
        stateVariables = (AppState)deserializer.Deserialize(stateStream);
        // 同步静态变量值
        roundsPlayed = stateVariables.roundsPlayed;
        money = stateVariables.money;
        totalMoneyEarned = stateVariables.totalMoneyEarned;
        totalScore = stateVariables.totalScore;
        totalKills = stateVariables.totalKills;
        totalLosses = stateVariables.totalLosses;
        // 原有已实现的变量赋值
        equipedShield = stateVariables.equipedShield; 
        equipedWeapon = stateVariables.equipedWeapon; 
        healthPotionCount = stateVariables.healthPotionCount; 
        playerExpEarned = stateVariables.playerExpEarned;
        // 其他AppState中定义的属性如果有对应静态变量，在此处补充赋值即可
    }
}
