We urgently need expert Apple engineers to help us Thread 36 Crashed:

I had the same problem, did you solve it?

I also encountered the same problem, the Main Thread Checker that opened Xcode has not been able to track the specific location, but there is this crash feedback online every day. At present, I check that all devices with iOS 16.0 system or above appear, and we need the official to help us solve this intractable problem 我也遇到同样的问题，开启Xcode的Main Thread Checker始终没有追踪到具体位置，但是线上每天都会有这个奔溃反馈，我目前查看都是iOS 16.0系统以上的设备出现，需要官方来帮助我们解决一下这个棘手的问题

Instrument：App Launch & Time Profiler tool instead

iOS 15 have new dyld,so it not work any more
