Layout Crashing when using Configuration

[MKa]

I have a custom application in which i remove all tools and tabs except for my tools located in my config.daml using this code in the ConfigurationManager.  All of my tools are used on the Map Tab.

protected override void OnUpdateDatabase(XDocument database)
        {

            var nsp = database.Root.Name.Namespace;
            
            // select all elements that are tabs
            var tabElements = from seg in database.Root.Descendants(nsp + "tab") select seg;
            // collect all elements that need to be removed
            var elements = new HashSet<XElement>();
            foreach (var tabElement in tabElements)
            {
                // skip root and backstage elements
                if (tabElement.Parent == null || tabElement.Parent.Name.LocalName.StartsWith("backstage"))
                    continue;

                var id = tabElement.Attribute("id");
                if (id == null || id.Value.StartsWith("MYIDS"))
                {
                    continue;//Skip our tabs
                }
                
                elements.Add(tabElement);
            }
            // remove the elements
            foreach (var element in elements)
            {
                element.Remove();
            }
        }‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍

I think this might be an easy one, but I need to figure out why my application crashes when I load a layout from the code behind.  This opens a layout tab.  But when I click on one layout element (Text Element).  The config application crashes with the following errors.  My guess is this must have something to do with, when clicking on the Text Element in the layout tab, no menu exists for that Text Element?  I think I need to add back in the layout menus and Tabs.  But I really want my uses to only be able to use tools that I show in my configuration.

I was able to just add some analysis tabs that I wanted and the crashing went away.  I remove the analysis and view tab using this code inserted into my above logic.  

if (id == null || id.Value.StartsWith("esri_layouts"))
                {
                    //We don't want to see the analysis or view tab
                    if (!id.Value.Contains("esri_layouts_analysisTab") && !id.Value.Contains("esri_layouts_viewTab"))
                    {
                        continue; //Skip all Layout but analysis and view
                    }
                }‍‍‍‍‍‍‍‍
