How to remove standalone table from contents

Question

Hello! I am trying to remove a specified standalone table from the Contents pane. Here is the code I have so far:

try
{
     var mapView = MapView.Active;
     if (mapView != null)
     {
          var map = mapView.Map;
          if (map != null)
          {
               foreach (StandaloneTable table in map.StandaloneTables)
               {
                    if (table.Name.Contains("K Factors"))
                       map.RemoveStandaloneTable(table);
               }
          }
     }
}
catch (Exception ex)
{
}

There may be multiple tables whose name contains "K Factors" and that's ok -- I would like them all removed.

I noticed that map.StandaloneTables is a ReadOnlyObservableCollection and I'm not sure if this has to do with the exceptions that I'm getting.

The exception says either, {"Class not registeredClass not registered"} or {"Access is denied. (Exception from HRESULT: 0x80070005 (E_ACCESSDENIED))"}

Any help would be appreciated.

The RemoveStandaloneTable() method must be called on the MCT. Try this: QueuedTask.Run(()=> { map.RemoveStandaloneTable(table); } ‍‍‍‍ See Working with Multithreading in ArcGIS Pro for more information.
