Solution: As suggested I changed load autoLoad="true" in my Module in the config.daml. I moved my long running task into the OnToolActivateAsync event with wrapper code to ensure it only is run the 1st time the button/Tool is clicked on the Ribbon. I Activate the tool with FrameworkApplication.State.Activate in the initial class constructor and setup a new event handler to 'catch' all UI codes that are not caught explicitly within the application this (1) protects ArcGIS Pro itself from crashing and (2) allows me to do .Deactivate if the add-in has an unhandled error. In the modules class,  defined in the config.daml as SRView4ProTool, I update the constructor as follows and configured the data handler.   public SRView4ProTool() { if (getEnterpriseTableConnection() == null) //if this is null then this is the first time clicked on the add-in during the session, this could just be a public static int runCount but I'm using my data connection that was setup in OnToolActivateAsync { // Add the event handler for handling UI thread exceptions to the event. Application.ThreadException += new ThreadExceptionEventHandler(ErrorHandler_UIThreadException); // Set the unhandled exception mode to force all Windows Forms errors to go throughour handler. Application.SetUnhandledExceptionMode(UnhandledExceptionMode.CatchException); //set the state FrameworkApplication.State.Activate("srview_state"); } IsSketchTool = true; SketchType = SketchGeometryType.Point; SketchOutputMode = SketchOutputMode.Map; } I then add the event handler code private static void ErrorHandler_UIThreadException(object sendor, ThreadExceptionEventArgs t) { DialogResult result = DialogResult.Cancel; result = MessageBox.Show("Fatal Windows Form Error. Would you like to try to continue OR Cancel/Close the Add-In?", "Fatal Windows Forms Error", MessageBoxButtons.OKCancel, MessageBoxIcon.Stop); // Exits the program when the user clicks Cancel. if (result == DialogResult.Cancel)   {   formResults.btnClose_Click(sendor, t);   FrameworkApplication.State.Deactivate("srview_state");   } } ...
