xyzApp is the placeholder for the app name. I m unable to replicate the crash .
Please help me out. This crash is present in the ipa that is uploaded to App Store with live url(production url). It is a universal app.
Just for reference:
Device details for which the crsh has occurred:
DEVICE
3rd Gen iPad, CDMA
OS
iOS7.0.3
Thanks in advance.

Looks like you haven't symbolicated. That helps a lot when debugging with Crittercism. Here's the documentation Crittercism provides around getting the symbols onto the server for iOS:
http://docs.crittercism.com/ios/ios.html#configuring-ios-symbolication
If you're having trouble uploading symbols to Crittercism, then contacting there support might be your best bet.

It seems to happen only on iphone. What could this be? Are there ways I could get more info on this error. I don't see any of my code in the stack trace.
EDIT:
Also posted it to the flutter repo
https://github.com/flutter/flutter/issues/94286

AudioToolBox crash report only in iOS 12.3 above OS apple devices

From iOS 12.3 and above iOS versions we are getting AudioToolBox crashes, we do not know why these crashes are happening. We have Crashlytics Crash report but we are not able to debug the issue with the help of Crashlytics crash report.
I have attached the Crashlytics crash report.
Background of our application :
Our application streams the video using RTSP url and VLC mobile kit. even when the application is sent to the background the streaming continues and the stream will try to reconnect when the stream disconnects due to some error.
While streaming the video in the background we show the user a red bar on the user iPhone.
We tried different scenarios to reproduce the issue some of them are
1) we checked if it is happening when we receive a mobile call when the user is streaming
2) We checked if interruptions from other streaming applications are causing the issue
3) We checked if Siri or getting a face time call is creating the crash
We tried all the above mentioned in debugging, as well as release, builds
find the crash report details​ below

Phonegap On Resume App Crash

Whenever my app is resuming from lock screen in iOS7, it is getting crashed. The problem is coming mostly in iOS7 devices and it is happening only when the screen is getting locked out automatically. When the I unlock the screen and press any html div or button in the app, the app crashes.
I already tried the solution posted here -
Workaround for PhoneGap, EXC_BAD_ACCESS on getDeviceInfo . It doesn't work.
The Crash log is below -
Exception Type: EXC_BAD_ACCESS (SIGSEGV)
Exception Subtype: KERN_INVALID_ADDRESS at 0xbe4008d4

i think u have a issue when ur app back in foreground from the background ,so it's happens due to when u r trying to access some data or array on background to foreground.that var or array wont accessible or u defined dynamic value thats why it's cause crashed .

Having trouble understanding a crash report with no related methods from my code

Looks like it's related to the network thread, most other threads are in a "mach_msg_trap" state. The 4th thread on the list is the one that crashed. I'm using AFNetworking on iOS 7.1
I appreciate any idea or thought that might help me investigate this issue.

It seems that you need investigate calls of these functions: mach_msg_trap and semaphore_wait_trap. It is the main reason of crash. Sometimes calls of these methods at the top of stack are indicators of receiving deadlock. Here some links for investigation:
IOS semaphore_wait_trap on main thread causing hang in UI
http://iphonedevsdk.com/forum/iphone-sdk-development/7354-what-means-mach-msg-trap.html
Deadlock using AFIncrementalStore and NSFetchedResultsController
Try to reproduce crash by starting application, open url connections, send application to background, wait few seconds and then bring it to foreground.

I update my app today. The strange behavior has come only when the app is updated. If users reinstall the app it work fine.
Based on:
Application Specific Information: com.myapps failed to launch in time
Elapsed total CPU time (seconds): 4.420 (user 4.420, system 0.000),
10% CPU Elapsed application CPU time (seconds): 0.714, 2% CPU
it looks like your app is not returning from application:didFinishLaunchingWithOptions: in time.
You are probably doing something in that method that is blocking the thread and preventing it from returning.
