从iOS 12.3和更高版本的iOS版本开始，我们将收到AudioToolBox崩溃，但我们不知道为什么会发生这些崩溃。我们有Crashlytics崩溃报告，但无法在Crashlytics崩溃报告的帮助下调试问题。
我附上了Crashlytics崩溃报告。
我们的应用程序背景：
我们的应用程序使用RTSP网址和VLC移动套件流式传输视频。即使当应用程序发送到后台时，流继续进行，并且当流由于某些错误而断开连接时，流将尝试重新连接。
在后台流式传输视频时，我们在用户iPhone上向用户显示一个红色栏。
我们尝试了不同的情况来重现其中的一些问题
1）我们检查了用户在流式传输时接到移动电话时是否正在发生
2）我们检查了其他流应用程序的中断是否导致了问题
3）我们检查了Siri还是接到电话打扰了
我们在调试以及发行版本中尝试了上述所有内容
在下面找到崩溃报告详细信息
