I have checked on various platforms for this issue. But have not found any solution related to it.Please provide any solution related to it.
It is crashing on app launch itself and this is the report it shows on fabric
I've the same issue on iOS 13 and it's my most serious crash on Crashlytics.
It occurs only in iOS 13 and above. Unfortunately also in the latest 13.1.2.
Starting by the iOS 13 release I've detected a strange warning when I put my app in background the debug console print Can't end BackgroundTask: no background task exists with identifier x, or it may have already been ended. Break in UIApplicationEndBackgroundTaskError() to debug.
Maybe the issues are related.

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 am seeing the following crash log in Crashlytics with an iOS app. It is certainly infrequent, and I have been unable to replicate, but it is very annoying.
Anyone able to suggest what this is likely linked to?

I just made some updates to my app, and have been seeing some new crash reports in TestFlight that I can't find much information on online. Can anyone help me interpret what's going on here? It's happening in different places throughout my app, so I don't think it's related to one specific function...
