此崩溃远远超过了我们的崩溃日志，我们只是无法弄清楚是什么原因造成的。因此，我向你们寻求帮助。
我对此主题的研究表明，可能的原因是，我们要么尝试以与游戏使用的方向不同的方向展示广告，要么我们以不同于最小化的方向恢复应用。看起来这是2016年的事情，在Unity 5.6.0中已解决。但这并没有太大帮助，因为我们当前正在使用Unity 2018.4.6f1。
我们无法自己重现此崩溃，但在Firebase Crashlytics上却看到大量类似的崩溃。这就是我们要做的所有事情。
以下一些相关信息：
团结：2018.4.6f1
受影响的设备：iphone，ipad
受影响的操作系统：iOS 9-iOS 13
Xcode版本： 11.1
Unity播放器设置配置：
默认方向：自动旋转
使用动画自动旋转：true
允许自动旋转的方向：横向右，横向左
