FilePicker doesn't exit after selecting a valid director (tested on Mac)

Describe the bug

The FilePicker in the Flutter application does not exit after selecting a valid directory. The application is expected to exit the FilePicker and return the selected directory path when a valid directory is selected. However, it continues to ask for a directory even after a valid one is selected.

Steps to reproduce

Run the application.
When prompted, select a directory using the FilePicker.
Choose a directory named 'אוצריא'.
Notice that the FilePicker does not exit and continues to ask for a directory.

Expected behavior

After selecting a valid directory, the FilePicker should exit and return the selected directory path. The application should then proceed with its next steps using the selected directory.

Environment

OS: macOS
Flutter version: 3.22.2

Additional context

The relevant part of the code is in Main.dart, in the main function:

void main() async {
  WidgetsFlutterBinding.ensureInitialized();
  await () async {
    //first try to get the library path from settings
    String? libraryPath = Settings.getValue('key-library-path');

    ....
    // here's the relevant code that causes the fail
    while (libraryPath == null ||
        (!Directory('$libraryPath${Platform.pathSeparator}אוצריא')
            .existsSync())) {
      libraryPath = await FilePicker.platform
          .getDirectoryPath(dialogTitle: "fzהגדר את מיקום ספריית אוצריא");
      Settings.setValue('key-library-path', libraryPath);
    }
  }();
  runApp(const OtzariaApp());
}

where the application asks the user to select a directory. The loop should exit when a directory named 'אוצריא' is selected. However, even after selecting a directory named 'אוצריא', the FilePicker doesn't exit and keeps asking for a directory.

It never exits this window:
