Solution

1. Locate the GetBalance function in your MinimalistHud.cs file.

2. You will find something similar to this:
 

private double GetBalance(BasePlayer player)
{
    if (config.economicsPlugin.ToLower() == "economics" && Economics)
        return Economics.Call<double>("Balance", player.userID);
    else if (config.economicsPlugin.ToLower() == "iqeconomic" && IQEconomic)
        return (double)IQEconomic.Call<int>("API_GET_BALANCE", player.userID);

    return 0;
}

3. Replace it with the following code to handle possible null values:

 private double GetBalance(BasePlayer player)
        {
            if (config.economicsPlugin.ToLower() == "economics" && Economics)
                return Economics.Call<double>("Balance", player.userID.Get());
            else if (config.economicsPlugin.ToLower() == "iqeconomic" && IQEconomic)
                return (double)IQEconomic.Call<int>("API_GET_BALANCE", player.userID.Get());

            return 0;
        }

Thanks
