GenericParameters InvalidOperationException @ GetType

I want to import a xml file that allows creation of objects dynamically. I realize that I need to use reflection. Below is an img of the error that tries create an instance of a class via the Type.GetType method. But it is returning an error and never goes to next line. I included the class it is trying to instigate.

Below is the class in question

  public class AuthenticationWorker : Worker
{
    public AuthenticationWorker():base()
    {
    }
    protected override Task<object> DoWork()
    {
        throw new NotImplementedException();
    }
    protected override void Initalize(params string[] parameters)
    {
        foreach (var param in parameters)
            System.Diagnostics.Debug.WriteLine(param);
    }
}

And this is the abstract class Worker

  public abstract class Worker
{
    public enum LogLevel
    {
        Debug = 0,
        Warning = 1,
        Error = 2
    }

    public Worker()
    {

    }

    protected List<KeyValuePair<LogLevel, string>> Logs;
    protected Dictionary<string, string> Parameters;
    protected Dictionary<string, object> MetaData; 
    public void AddLog(LogLevel logLevel, string description)
    {
        if (Logs == null)
            Logs = new List<KeyValuePair<LogLevel, string>>();
        Logs.Add(new KeyValuePair<LogLevel, string>(logLevel, description));
    }

    abstract protected Task<object> DoWork();
    abstract protected void Initalize(params string[] parameters); 
}
