System.Reflection.TargetException: Object does not match target type

I have two dlls right next to each other in a directory. When I load an assembly invoke a method from DLL A onto DLL B then invoke a method from DLL B back onto DLL A, but it fails at the last step and throws the following error

 System.Reflection.TargetInvocationException: Exception has been thrown by the target of an invocation. ---> System.Reflection.TargetException: Object does not match target type.
    at System.Reflection.RuntimeMethodInfo.CheckConsistency(Object target)
    at System.Reflection.RuntimeMethodInfo.InvokeArgumentsCheck(Object obj, BindingFlags invokeAttr, Binder binder, Object[] parameters, CultureInfo culture)
    at System.Reflection.RuntimeMethodInfo.Invoke(Object obj, BindingFlags invokeAttr, Binder binder, Object[] parameters, CultureInfo culture)
    at System.Reflection.MethodBase.Invoke(Object obj, Object[] parameters)
    at ServerSDK.BootStrapper.GetPlayerSteamID(UInt16 playerid)

And here is the code.

public void Init()
{            
    string assemblyFolder = Path.GetDirectoryName(Assembly.GetExecutingAssembly().Location);
    string file = Path.Combine(assemblyFolder, "NetworkSystem.dll");
    Assembly assembly = Assembly.LoadFile(file);
    type = assembly.GetType("ScriptingAPI.ScriptEngine");

    getSteamMethod = type.GetMethod("GetSteamID", new Type[] { typeof(ushort) });
    Console.WriteLine("bootstrap module executed");       
}

public static string GetPlayerSteamID(ushort playerid)
{
    var steamid = getSteamMethod.Invoke((object)type, new object[1] { playerid });
    return steamid.ToString();
}

and here is the method that from DLL A I am attempting to invoke

public string GetSteamID(ushort playerID)
{
    Console.WriteLine(playerID.GetType().Name);
    return connectedPlayers[playerID].steamID;
}

Also I feel like I need something like Activator.GetInstance instead of CreateInstance as the DLL is already running and if i was to use CreateInstance it would in turn throw null reference exceptions.

Alright so the solution for me in this case was to pass the object that invoked Init along as a parameter with it. Thank you for the replies though!
