Hello @darkpaw, we started observing an increase in crashes on October 24th, 2022 - this was the day when iOS16.1 was released. We see few pattern: it's crashing only on iOS16.1 and later it's crashing on already released versions, that worked before without crashes it's crashing not only in our code (where we deserialise JSON via Decodable), but also in 3rd-party-libraries (Lottie (https://github.com/airbnb/lottie-ios/issues/1826), App-Auth (https://github.com/openid/AppAuth-iOS/issues/737)) in all of these crashes we can see either JSONDecoder (via Lottie) or NSJSONReader (via App-Auth), which somehow points to JSON-decoding in such cases Do you know if anything related to that has changed in iOS16.1, which would explain such crashes suddenly? Cheers, Andy

@darkpaw I created FB11844108 and added two crash-reports to it. Hope this help. Thanks, Andy

Hello, we started seeing this issue also today (suddenly). Not sure yet why this suddenly came up
