try:
            transaction = Transaction(doc, "Export View: " + view.Name)
            transaction.Start()
            result = doc.Export(folder_path, safe_view_name + ".nwc", export_options)
            transaction.Commit()

            if result:
                print("{0} adlı görüntü başarıyla dışa aktarıldı.".format(view.Name))
            else:
                print("{0} adlı görüntü dışa aktarılamadı.".format(view.Name))

So based upon your post: result is False. No Export was made.
I would have expected your print “Export işlemi sırasında hata:” to show something. What does it say?

Btw. I believe you can leave NavisExportOptions() as it is.
Default value for ExportScope is model.
ViewId is only used when ExportScope = View.

export_options = NavisworksExportOptions()
export_options.ViewId = view.Id
export_options.ExportScope = NavisworksExportScope.Model  # Daha genel bir kapsam deneyelim

export_options = NavisworksExportOptions()
