Flutter Windows应用程序未在发布模式下启动

我刚刚在Windows上创建了一个flutter项目

flutter create appname --platforms=windows,macos

现在我可以启动这个Windows应用程序

flutter run -d windows

一切都很完美。但问题是我无法在发布模式下启动Windows应用程序。我试过：

flutter run --release -d windows

但是应用程序窗口没有显示。我只看到任务管理器中运行的进程。没有必要向您显示项目的代码，因为它是您使用flutter create获得的模板项目。没有修改单行。
发布模式适用于所有其他平台，包括web和macos。我也尝试手动启动.exe文件，但也不起作用。我也尝试更改为flutter的主版本，但它也不适用于最新的主版本。
flutter doctor -v没有显示任何错误：

看起来这是Flutter的一个bug？
编辑windows/runner/flutter_window.cpp，替换此行：

flutter_controller_->engine()->SetNextFrameCallback([&]() {
    this->Show();
});

用这个：

this->Show();

如果你像@Zensonaton的回答中提到的那样编辑windows/runner/flutter_window.cpp，它就可以工作。但是我通过在MaterialApp中添加restorationScopeId来修复它，如下所示：

class MyApp extends StatelessWidget {
  const MyApp({super.key});

  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      restorationScopeId: "Test", // <-- Add this line
      home: Scaffold(
        body: Container()
      )
    );
  }
}
