Firebase Crashlytics shows a weird crash on iOS app, I can't understand what causing it:

I try to fix an error on firebase.
My sources are based on objective-c, and "webkit" is a problem in my code
I try and try to find what is cause of it, but I can't. Because these errors appears in a different places but same error.

I know it has only few clues for finding. Sorry.
My codes have a lot of request datas to Server and response from Server on mainthread.
I expect it occurs this problem but I'm not sure.
Thanks.

This crash is happening only on iOS 13.3.1 & 13.4.0
This crash is happening randomly and is a real deterrent to my customers.
I have update fabric library to lastest version (1.10.2).

Please help me in identifying where the problem actually starts, is it starts at AFURLSessionManagerTaskDelegate (or) MySDK ?
Which is causing the issue, is NSLog causing issue ? or blocks and threads causing this issue?
How to analyze a crash report is described in Technical Note TN2151.
I get the following crash log from Crashlytics for my app. My code do not call msgpack_zone_free or msgpack parse method at all and so I'm confused how that happened. I'm unable to reproduce this crash myself so I'm left to analyze the issue from the crash report itself. Any pointers to what I need to check will be very helpful.
This is not a case of low memory as I see free memory from Crashlytics.
