ADDITIONAL SYSTEM INFORMATION :
Windows 7 / 10 64bit, Java OpenJDK 19.0.1+10-21, JavaFX 21.0.4

A DESCRIPTION OF THE PROBLEM :
When I call fileChooser.showOpenDialog the file chooser is displayed correctly. When I browse the attached Android phone storage (did not test with iPhone, lack of iPhone) I can see all the files. When I select a file, the dialog returns to the java code, but the result is NULL (the selected file is NULL). No exception is thrown.

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
Attach an Android phone to your windows system. Create and show a javafx file chooser dialog, browse a file from the attached phone's storage and open it.

EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
a valid File object is returned
ACTUAL -
NULL is returned
