Compiled version not working because of path

Hello,
I have compiled similar programs successfully with earlier versions (e.g. 2017a), but now in 2019b have this issue.
Get this message in testing the software:
![ctrlv error.png](https://www.mathworks.com/matlabcentral/answers/uploaded_files/268179/ctrlv%20error.png)
Here is the code that may be a problem. I also use the utility uipickfiles() from file exchange. Never use "addpath" itself. How do you find files if not like this?
% Plot the logo
[~,lingo] = dos('set username');
login = lingo(10:end-1);
% Plot the background and the logo: Background on axes2, logo on axes3
dir_name = ['C:\Users\',login,'\Desktop'];
wiggle_file_name = [dir_name,'\wiggles3.jpg'];
if exist(wiggle_file_name,'file')
imshow(wiggle_file_name);
end
logo_file_name = [dir_name,'\ctrl_v_logo.jpg'];
% imshow(logo_file_name); % Overwrites axes2
imshow(logo_file_name,'Parent',handles.axes3);
Any thoughts? This part is just to put a logo on the screen to start the program -- used to work! I'm not sure if the error occurs elsewhere, though.
I advise the user to put the installer on the Desktop as well as these figures.

If you are certain that the image you are looking for is always going to be on the Desktop and your OS is Win10, you can try the following line of code. This should work for Win8 as well, but am not certain about other OSs. I use this line of code frequently with trying to setup a splahscreen for my apps and executables, and have done so in the latest version of MATLAB.
dir_name = ['C:\Users\',getenv('USERNAME'),'\Desktop\'];

I typically use uigetfile for initiating user file selections. I also like to assign a default starting directory when using uigetfile and its counterpart uiputfile in my GUIs. As I delve further into using this GUI, I generally have a project folder that I save and access pertinent files and it makes sense to update this default directory. The following is a short example of how I might call this function and update it if changed within a GUIDE GUI.
...
[fn,pn] = uigetfile(fullfile(handles.startdir,'*.mat'),'Select Project File','MultiSelect','off');
if ~isnumeric(pn)
handles.startdir = pn;
end
...
% Update handles structure
guidata(hObject,handles);

You need to modify your startup.m so that it does not add anything to the search path if isdeployed() is true.

startup.m gets called automatically when MATLAB is started, provided it can find one in the path at the appropriate location.
Because MATLAB assumes that startup.m is setting important local customizations that are going to be needed by the MATLAB code, then MATLAB Compiler automatically looks for startup.m and incorporates it as part of the executable, to be run before the function that you designate as the entry point.

However even if you place the cd() or addpath() command in the "if ~isdeployed" block, it will still warn you -- I know from experience. In that case, just ignore the warning.
