Hello. We've been collecting a lot of device feedback crashes, but we've been unable to reproduce them and can't fix them 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 The stack in the xccrashpoint file does not provide effective stack information, so I cannot locate the specific bug. We have not been able to reproduce the problem using Xcode, so we need your assistance. I have also seen many people on the forum with similar feedback, but nothing seems to come to fruition https://developer.apple.com/forums/thread/129686?login=true&page=1#775136022
