您需要编辑运行配置并取消选中在外部控制台上运行"框，然后它就会运行得很好.目前，flatpak 容器内没有外部控制台应用程序，因此无法在外部控制台上运行.

You will need to edit the run configuration and uncheck the box that says "Run on external console," then it will run just fine. Currently, there is no external console application inside the flatpak container, so it is not possible to run on the external console.
