Unable to recover NinjaTrader custom assembly

[blar58]

When I try to reload Ninjascript from a chart it just freeze.
I have to close NinjaTrader with the Task Manager and when I reload NinjaTrader
I get an error message that NinjaTrade cannot recover the custom assembly.
I have attached the error message.

Context :
It does that only for an indicator that I converted from NT7.
It does it only on the second time I apply the indicator. Goes through well the first time.


I suspect it may come from the state.teminated.
Do you see something that could cause the problem from my code :

 if (ChartWindow != null)
{
   //Dispatcher used to Assure Executed on UI Thread
     this.Dispatcher.Invoke((Action)(() =>
   {	
       //Button Null Check
       if(NewsButton != null)
   {
       //Remove Button from Indicator's Chart ToolBar
       ChartWindow.MainMenu.Remove(NewsButton);
       //Remove Button Event Handler
       NewsButton.Click -= NewsButton_Click;
       //Set Button to Null - Not Needed - Done out of Habit
       NewsButton = null;
   }
       //Remove Tab Changed Event Handler
       ChartWindow.MainTabControl.SelectionChanged -= TabChangedHandler;
       //Set ChartWindow to Null - Not Needed - Again Just Done out of Habit
       //ChartWindow = null;
}));
					
       //Dispatcher used to Assure Executed on UI Thread
       this.Dispatcher.Invoke((Action)(() =>
       {	
       //Button Null Check
       if(HelpButton != null)
       {
         //Remove Button from Indicator's Chart ToolBar
         ChartWindow.MainMenu.Remove(HelpButton);
         //Remove Button Event Handler
         HelpButton.Click -= HelpButton_Click;
         //Set Button to Null - Not Needed - Done out of Habit
         HelpButton = null;
}
         //Remove Tab Changed Event Handler
         ChartWindow.MainTabControl.SelectionChanged -= TabChangedHandler;
         //Set ChartWindow to Null - Not Needed - Again Just Done out of Habit
         //ChartWindow = null;
}));
					
					
           //Dispatcher used to Assure Executed on UI Thread
           this.Dispatcher.Invoke((Action)(() =>
           {	
              if( SkipRemoveUpdater == false )
	{
	 try
	 {
	  GlobalVariables8.ResetDictionariesForInstrument( this.Name+Instrument.MasterInstrument.Name+Instrument.Expiry+Bars.BarsType.DisplayName+BarsPeriod.Value );
	  GlobalVariables8.DisposeUpdater( this.Name+Instrument.MasterInstrument.Name+Instrument.Expiry+Bars.BarsType.DisplayName+BarsPeriod.Value );
                }
	   catch(Exception e)
	   {
	       Print(" An error occured : "+e.Message);
	    }
}
					
	     GlobalVariables8.UnSubscribe("globalLandscapeDict",this);
}));
									
					
                    ChartWindow = null;
}
