Appdesigner EditField not updating while simulink model is running

Hi

I am attempting to create an app which continusouly runs a simulink model and updates editfields in the application to match current simulink data. To do this I have a model with infinite runtime and an application with a timer that periodically pulls the 'Value' parameter of a constant block. The timer runs and pulls the requested data (tested by printing to cmd windwow) however it is not updating the editfield while the model is running.

I have the model set up for simulink realtime but I have confirmed that is not the issue as it runs the same in normal mode as well. I've also tried running the model/timer at several rates which seems to make no impact.

When run the timer seems to work and update vlaues for a short period of time before the model fully initalizes and then stops so I know that the code is capable of correctly updating the expected fields. Any advice on how to get those fields to update while the model is active?

While running:

While stopped:

    properties (Access = private)
        CurrentState = 0; % Last button press state
        Updater % Object to hold update timer
    end
    
    methods (Access = private)
        
        function getstate(app,~,~)
            app.TimerCheckEditField.Value = app.TimerCheckEditField.Value+1;                % Check to see how many times the timer has run
            LampVal = str2double(get_param(['RealTimeAppInterface','/ConFlip'],'Value'));   % Get the value of the constant block
            app.ValEditField.Value = LampVal;                                               % Set the 'Val' editfield to the current block value
            if LampVal                                                                      % Change lamp color depnding on value
                app.Lamp.Color = [0 1 0];
            else
                app.Lamp.Color = [1 0 0];
            end
        end
    end
    

    % Callbacks that handle component events
    methods (Access = private)

        % Code that executes after component creation
        function startupFcn(app)
            set_param('RealTimeAppInterface', 'SimulationCommand', 'start')                         % Start the model
            app.Updater = timer('Period',1/10,'ExecutionMode','fixedRate','TasksToExecute', Inf);   % Set up update timer
            app.Updater.TimerFcn = @app.getstate;                                                   % Set up timer funtion
            start(app.Updater)

Try throwing in a

somewhere to force an immediate screen update.
