I created a standalone executable version of a GUI but it opens the GUI for an instance and crashes with "not enough input arguments" error, when run from a folder that does not contain the related GUI .m/.fig files, for e.g. while running directly from the desktop. The line of error is from the main GUI m-file shown below. The application runs as expected when run from the folder containing all the accompanying files.
I was also trying to create a python package of the same GUI, but a similar experience with the GUI not staying open. Simply shows the GUI instantaneously but closes immediately with no particular error message.
