【问题描述】：
我们已将 BlackBerry Dynamics SDK 集成到我们的 iOS 应用程序中，该应用程序也使用 Firebase 分析。在运行 iOS 12/13 的设备上一切正常，但在运行 iOS 14 的设备上，初始化 Firebase 时应用程序崩溃。
BlackBerry 授权正常，一旦用户获得授权，就会执行初始化 Firebase 的代码并发生崩溃。
BlackBerry Dynamics SDK 版本为 8.1.0.37，我们使用的是动态库而不是静态库。
BlackBerry Dynamics 文档说明如下：
需要 SDK 版本 8.1 才能在 iOS 上支持 FirebaseCore 14. FirebaseCore 与 iOS 14 上的 SDK 8.0 或更低版本不兼容。如果不使用 FirebaseCore pod，应将其移除 由应用程序。
这里是调用栈：

这是打印到控制台的内容：

有人知道有没有办法解决这个问题？
