Description
Steps to reproduce:
1. Build and deploy qtbase/examples/widgets/gestures/imagegestures .

3. Open (Device)/DCIM/Camera(actually /storage/emulated/0/DCIM/Camera) folder in FileDialog.
4. Tap "Use this folder"
5. Tap "Allow" to "Allow imagegestures to access files in Camera?" dialog.
6. App crashes and application output says like this.

Listing files in the directory seems to succeed but QFile cannot open individual file in the directory.
NOTE:
KDAB's example does similar thing and works fine.
https://github.com/KDAB/android/tree/master/examples/shared_storage
ContentResolver in this example calls Android API's "takePersistableUriPermission" for each file in the directory.
But in Qt6.5 it is implemented in QAndroidPlatformFileDialogHelper::takePersistableUriPermission() and it is private method.
So there is no way to take permission for each file without QFileDialog.
