This is what I have been using in the meantime:

  StorageFolder? programDataFolder;
  
  FolderPicker folderPicker = new FolderPicker();
  InitializeWithWindow.Initialize(folderPicker, App.MainWindow.GetWindowHandle());

  folderPicker.ViewMode = PickerViewMode.List;
  folderPicker.SuggestedStartLocation = PickerLocationId.DocumentsLibrary;
  folderPicker.FileTypeFilter.Add("*");

  ProgramDataFolder = await folderPicker.PickSingleFolderAsync();
  if (ProgramDataFolder != null)
  {
    //use folder chosen
    App.ProgramDataFolder = ProgramDataFolder.Path;
    
  }
