This is a duplicate of bug #54607.

As workaround, in the "General" tab of the GUI preferences there is an option "Use native file dialogs" to uncheck in your case.

SUMMARY
The GNU Octave Directory Browser window, on first use, hangs for many tens of seconds then disappears. Subsequently it works OK. 


STEPS TO REPRODUCE
1. Boot system
2. Start GNU Octave.
3. Click on folder icon to the right of the "Current Directory" text field.

OBSERVED RESULT
The windows hangs for many tens of seconds then disappears. Clicking on "Cancel" button or the window 'X' has no effect.

After the Directory Browser window has disappeared, clicking on the folder icon again produces the correct result.

Quitting and restarting Octave produces a similar effect except now, after the long pause, the Directory Browser window does not disappear but instead shows the content of the startup directory.
 

EXPECTED RESULT
Window displays the content of the directory specified by the Octave startup settings.

SOFTWARE/OS VERSIONS
Linux/KDE Plasma:
(available in About System)
KDE Plasma Version:  plasmashell 5.18.5
KDE Frameworks Version: 5.68.0
Qt Version: 5.12.8

ADDITIONAL INFORMATION
Kubuntu 20.04.1

Using the "Current Directory" text field/menu works as expected.

I have an Xubuntu 20.04.1 system with the same Octave version. This works as expected. Hence it might be something to do with interacting with KDE Plasma.
