Crash - Notification - EXC_BAD_ACCESS (SIGSEGV) - KERN_INVALID_ADDRESS - Namespace SIGNAL - ios

Kindly share your thoughts/suggestion on below crash.
Seeing some strange crashes and these crashes are not reproducible from my end but users reported so many similar crashes.Crash log says application is crashed in thread 0 and after the __CFNOTIFICATIONCENTER_IS_CALLING_OUT_TO_AN_OBSERVER__ call in thread 0 I can see a trace 0 ??? 000000000000000000 0 + 0...what does it mean?
Below is a sample crash log.All other crash logs looks same as below.

RevenueCat Purchases.configure crashes my Xcode app after 2 minutes in TestFlight

My Xcode app has RevenueCat Purchases.configure(withAPIKey: "myApiKey") which runs fine in a device from Xcode. The same app crashes in TestFlight after 2 minutes even if left alone. I commented out Purchases.configure and it stopped crashing in TestFlight.
I need help.

So I do see some errors but they are all non-specific, not pointing to a specific call.
Can I extract more info from this log or somewhere else to figure out what could have gone wrong?

can someone explain why these crashes keep occurring?
I don't think it makes sense to turn the NSDictionary into another NSDictionary with [NSDictionary dictionaryWithDictionary:] ... also NSDictionary can be non-nil but contain 0 key entries (an empty dictionary).
Perhaps you want: NSDictionary *apnsPayload = [userInfo objectForKey: #"alert"]; ?

iOS App Crash in unknown module-mdDoRequest mdlExchange mdlRemoteExec

The crash tools report a weird crash of my app.
It crashed at MDOSWebViewDelegate.
After listed all the symbols of binary with command nm -a myApp,
and still can't locate it from the crash stack.
I don't even know what features of these modules, it seems this module is from an System framework.
