Replace the Create() Method like this. It should Works. I tested this code on Unity 2018.2.8f1

private void Create ()
{
	CreateScript ();

        //Old Code
        /*if (CanAddComponent ())
			InternalEditorUtility.AddScriptComponentUnchecked (m_GameObjectToAddTo,
				AssetDatabase.LoadAssetAtPath (TargetPath (), typeof (MonoScript)) as MonoScript);*/

        //New Code
        if (CanAddComponent()) {
            // Need to use reflection to access this now (it is internal)
            MethodInfo addScriptMethod = 
                typeof(InternalEditorUtility).GetMethod(
                "AddScriptComponentUncheckedUndoable",
                BindingFlags.Static | BindingFlags.NonPublic
                );
            addScriptMethod.Invoke(
                null, new Object[] {
                    m_GameObjectToAddTo,
                    AssetDatabase.LoadAssetAtPath(TargetPath(),
                    typeof(MonoScript)) as MonoScript
                }
            );
        }
        //New Code End here

        Close ();
	GUIUtility.ExitGUI ();
}
