CALLBACK REMOVED !!!! in APP Designer

When loading my user interface it first correctly appears during a few seconds in the APP designer window, but after that the screen is cleared and the message CALLBACK REMOVED appears at the bottom of the screen.

In addition the following list of red messages (copy paste made them black) appears in the Matlab Home window,

     Error using appdesigner.internal.model.AppModel
     Error: File: AppModel.m Line: 610 Column: 44

      Warning: Error occurred while evaluating listener callback. 

This is happening with user interface in the today design process and with the backup version of yesterday.

I don't know how to recover from this situation.

José - where is the error message for "callback removed"? Is there more of the error message that tells us which callback is failing? Can you post the code for that callback?

Geoff,

I attach the photo of the APP designer window with the message CALLBACK REMOVED.

As I said before, the message appears during the process of opening my user interface without any other action from my side.

The sequence of events are as indicated namely, open my user interface file, once loaded it my design appears for a few seconds in the APP designer window, after that and for a few seconds again the CALLBACK REMOVED message appears.
