NO_CRASH_STACK crash in Xcode organizer crash reports, What's the reason and how can i fix it?

I'm also got a same issue. Does anyone found any solution yet in this thread.

I'm also got a same issue.

Does your app use a third-party crash reporter?

Seeing this in Xcode 13 Organizer, all NO_CRASH_STACK crashes come from iOS 15.0/15.1. @eskimo I'm not using any third-party tools.

Cool. Can you post an example crash report? For advice on how to do that, see Posting a Crash Report.

I also see a lot of different crashes suddenly appearing in iOS 15.0 / 15.1. All related to dyld (Project has been build with Xcode 12.2) -> Sample Crash log.

I recommend that you start a new thread for that because the underlying cause is unlikely to be related to the other crashes in this thread.

See Log below

Is that the full report? It seems weirdly short, but that might just be because it’s happening super early in your app’s startup sequence.

Also, when posting crash reports I’d appreciate you using a text attachment to avoid clogging up the timeline. For this and other hints, see my Posting a Crash Report post.
