runtime-error - Xcode 12.5 损坏 NavigationLink

Question

我刚刚将 Xcode 更新到 12.5 版。从那以后，我的 NavigationLink 代码出现了问题。将出现子视图，但是当我按下取消按钮返回父视图时，我在日志中收到错误消息。

无法呈现。请提交一个错误。

这在 Xcode 12.4 中没有发生。我恢复到 Xcode 12.4，问题就消失了。我安装了 12.5 作为辅助应用程序，并编写了一些通用视图来演示该问题。

我已经阅读并看到，如果我在一个视图上只有两个导航链接，则不会出现问题。但这将是对我的应用程序的重大重新设计......如果有的话，我真的可以使用更好的解决方案。TIA 鲍勃
