Compiling GUI to control Arduino

I wrote a simple GUI program in MATLAB that has a few button and sliders that control a stepper motor. The buttons are for up and down movement while the sliders control speed and amount of steps taken per click. I'm using the adafruit motor shield v2.0. When I run the GUI in MATLAB everything works fine, the buttons result in movement and the sliders control their designated variables. I need to compile this program to run on a stand alone (or at least with MATLAB compiler runtime). When I compiled it the GUI shows up but none of my buttons result in any functioning. Does anyone have an idea what's going wrong?

I have the same issue :/ Still havent found the fix. All that I know is that the standalone apps are not able to establish communication with the arduino. Probably missing out on a line of code or probably a file that has to be attached while compiling the standalone application.

I am having the exact same issue... Has anybody resolved this problem?

This error makes programming Arduino in Matlab almost useless if you cannot compile a GUI
