ios - 使用正确的导航项返回 ViewController 时 iOS13 崩溃

Question

我的应用程序现在在 iPad 上运行，它具有拆分 viewController 和 masterVC 是 navigationViewController 它有根 UITableViewController 和 als 有一个正确的 navigationItem。

好的崩溃步骤是..这里

1. 在 UISplitViewController 上触摸主 UITableViewController 上的 tableViewCell
2. 下一个 ViewController 将在 UISplitViewController 的主区域上推送到 tableViewController
3. 回到 UITableViewController
4. 现在它崩溃了

仅在 iPadOS13 设备上发生..

我用调用堆栈做了符号断点，以找出谁对崩溃负责，但真的很难知道崩溃的原因是什么

并且 backBarButton 默认箭头图像仅消失了 iPadOS13 设备请帮帮我..
