Me too. After iOS16.1, a large number of network flashbacks occurred. Now it is 16.3.1 and has not been solved.We've been giving feedback to Apple and haven't solved it yet. At first, Apple said it was the problem of their network.framework. Later, after I posted several similar questions in succession, Apple suddenly backtracked and said that the problem of our application was the memory problem. And they haven't given us any feedback yet, so I guess they don't care.A terrible process for developers.

OK. But I was kinda looking for a crash report, per my earlier post.

Apple crash report is here .I chose some of them because there were so many. Please check.Thanks

Here is another type of network apple crash report.This category is number one on our crash list. I chose some of them because there were so many. Please see the attachment.Please check.Thanks

I’ve seen a bunch of crashes like this from a bunch of different developers. Some of them were related to problems that we’ve already fixed but the latest round seems to be something new. While we have a bug to track this internally (r. 95907172) I recommend that you file your own bug about this.

Please post your bug number, just for the record.

Hi,I have file a bug report for network crash. bug number is FB12113130.I really hope you can deal with it as soon as possible, because there are a lot of crashes.Thanks

After iOS16.1, a large number of network flashbacks occurred. but On March 20th, the quantity suddenly decreased，I haven't found the reason yet
