        % Close request function: UIFigure
        function UIFigureCloseRequest(app, event)
            app.InstrumTab=app.UITable.Data;
            Instrum_Tab=app.InstrumTab;
            g=app.Setting.Instrument;
            save(g,"Instrum_Tab");       
            delete(app)

The first parameter passed to a UI Figure Close Request Fcn callback is not the app: it is the handle of the component that requested the callback (so, typically the handle of the uifigure)

Unless, that is, you configured the callback as an anonymous function that substitutes app for the normal first parameter.
