Recently we received lots of WKWebView crash logs on the iOS14 beta2 system.
Here is the crash log:
Exception Type: EXC_BAD_ACCESS (SIGBUS)
Exception Codes: 0x00000000 at 0xf7fff8018

Is anyone familiar with this? Thx in advance

we're getting a small number but regular crashes on launch in a production app.
We have Crashlytics and Sentry but i cant see any references to the react code.
Here is a couple of stacktraces

my only clue is from "initWithCoordinateSpace:orientation:scale:boundingPathBitmap" If there was a corrupt http image reference could this be causing a crash somewhere?
We are also using Firebase in-app-messaging. Could this be crashing the app on startup?
I'm unable to get which causes the application to crash. I'm having binary file and dSYM file along with crash report and I tried different ways (terminal commands) to symbolicate crash log but no luck. Please find the below crash information.

It's a large app, and I cannot identify which objectAtIndex is causing the issue.
After looking at similar issues, I added an Exception breakpoint:
However the breakpoint just keeps taking me back to the main.m file:
int main(int argc, char * argv[]) {
#autoreleasepool {
return UIApplicationMain(argc, argv, nil, NSStringFromClass([AppDelegate class]));
}
Can anyone point me towards how I can identify the line that is causing this exception?
Thanks!
Edit:
When I click on the My360 icon at the top of the debugging console, it shows this:
Today i tried running my app on my iPhone device, and it crashed! It worked perfectly fine on the simulator, I don't know what the problem is.

I have tried to look for the error, but I do not know what to look for. Can someone help solve this problem?
CCSprite initWithTexture: raises the exception that causes your app to exit. I'm not entirely up on Cocos2d but a quick check in the documentation suggests it raises exceptions on failure to find named files.
That being the case, I'd guess the problem is simply one of filename case. Macs are by default case insensitive. So if you have FunnyImage.png then the simulator will succeed if you attempt to load funnyimage.png.
iOS devices are case sensitive. So it will fail if you attempt to load funnyimage.png.
So probably what you want to do is check that all the filenames you've used in code exactly match the case of the actual files.
I notice that in my app's crash log on OS X that one of the first sections is "Application Specific Backtrace". It shows something like this:

What's the significance of "Application Specific Backtrace" and why isn't that code included in the main thread backtrace?
(To be clear, I'm not asking how to debug this code, I'm just looking for an explanation on the structure and meaning of the crash log itself. Thanks!)
This is how exception handling works. You have an exception on the main thread, where the NSException is created (it holds all info about exception including current stack trace). After throwing an exception object control is passed to the closest handler in the call stack, unwinding the stack between throw and catch point. If an exception is not caught, it is intercepted by a function called the uncaught exception handler. The uncaught exception handler always causes the program to exit but may perform some task before this happens.
The default uncaught exception handler logs a message to the console before it exits the program.
So in your case Application Specific Backtrace is the stacktrace when exception was thrown and Thread 0 Crashed:: Dispatch queue: com.apple.main-thread is the stack trace when the app was killed.
Notice that up to this point the stack trace is identical:
