Ios 调试libc++；abi.dylib:终止时出现std:：runtime\u错误类型的未捕获异常

我有一个Swift应用程序，它包括一个

ARScnView

，一个叠在上面的WebView，然后是一个叠在上面的ReactView。现在我的问题是：每5次重建/启动中就有1次（无所谓），我会收到一个终止崩溃，并显示以下消息：

libc++abi.dylib:以std:：runtime\u error类型的未捕获异常终止

在日志中绝对找不到更多信息。不管我是在模拟器上运行应用程序还是在实际的iPhone上运行应用程序。据我所知，metro bundler尝试加载本地react native bundle时会发生错误。由于调试原因，我延迟加载应用程序的每个组件。这是我的

由于这不是经常讨论的
libc++abi.dylib:以NSException（lldb）类型的未捕获异常终止
-错误，因此我完全不知道如何调试或消除它。请注意，在4/5次运行时，应用程序的行为完全符合预期，反应自然，一切工作都像一个符咒
