iOS 15 Crash : Foundation +[NSDateFormatter setDefaultFormatterBehavior:]

My App is getting crash on the user side but not able to reproduce it on our side. this issue is being reported via Crashlytics. Also, I am getting this crash issue in iOS 15 version but not getting any log for iOS 16 version. how I can catch this crash and fix it. any help will be appreciated.

Here is the crash log,

Do you have an Apple (not 3rd party) crash report for this? See the note about that from @eskimo in your other thread.

If this 3rd party report happens to be accurate, then you’ll need to take it up with the vendor of the closed-source SDK you are using.

But it would be unexpected for anyone to actually be calling setDefaultFormatterBehavior and extra unexpected for it to crash, so I’d suspect the crash report isn’t accurate. The crash may still be caused by that SDK but you need an Apple crash report to be sure.

Thank you for your response. I will check with SDK vendor.
