cannot launch a GUI which works previously

I am using Matlab 2019a. I have been using a 3rd party GUI script: uipickfiles.m to aid my dir selection.

The script stop functioning properly suddenly after months of using it. i did not do any upgrading of Matlab.

Issue:

• the GUI did not manage to popout. I did see an invisible window after i hover over my matlab icon at the taskbar but it cannot reveal itself after i click on it.
• When i try to terminate the script. the error is such:

>> uipickfiles

Operation terminated by user during uiwait (line 81)

In uipickfiles (line 644)

uiwait(fig)

I tried running some old executable files that includes this script, they are working fine.

However, if i compile a new executable file now with this issue, i faced the same problem when i run that exe.

I am not sure what is going on.

Did you ever get an answer to this? I'm having the same issue.

@Hannah Actor-Engel: Does you problem concern "uipickfiles" also? And is this function the function from the file exchange: https://www.mathworks.com/matlabcentral/fileexchange/10867-uipickfiles-uigetfile-on-steroids ?

If so, what is the preference for the figure position?

getpref('uipickfiles','figure_position')

Is it off screen?

You can also usually right-click that popout window and click the maximize button.

The maximum button works! And this is what I get: >> getpref('uipickfiles','figure_position')

ans =

2338 419 1277 494

How large is your screen? Reset the position property:

rmpref('uipickfiles', 'figure_position')

This worked! Thank you so much for your help!
