Hi all,
I am using uigetfile in a GUI I designed in the AppDesigner. After a couple of times of running the GUI, running other scripts, or using the debugger, I always get to the point where the uigetfile returns 0 without opening a selection window.
The only solution to work around this so far is to restart MATLAB every time which is quite annoying. Also I haven't managed to determine after which point this starts to happen.
I could post a working example, but in the simplest of cases, the easiest way to test that is by typing uigetfile in the command window, which will either work/not work as I described above.
Below is my MATLAB version running in MacOS Monterey 12.4

Just a wild guess but 0 is normally returned when user clicks on close button. May be MATLAB or OS (I don't know Mac OS at all) has a stacks of callback events. You might try to put
drawnow
before uigetfile to clear the pending pending callback.
You might also want to try to set the properties of the parent GUI component 'BusyAction' to 'drop' and 'Interruptible' to 'off'.
