We also have the same issue on iOS 14+ and iOS 12.2 devices.
Here also our stack trace which is quite similar to the others that are posted here:

@ElfSundae If the AFNetworking keep sending requests and got no responses from the API, after a huge amount of requests, it may crashed

[ElfSundae]

@Zzzzzzzack Thank you for the information, could you please provide a demo project for this case?

[SwifterBit]

same issue

[Zzzzzzzack]

This issue may occur if we are not using the AFURLSessionManager as a singleton.
I call the [invalidateSessionCancelingTasks:resetSession] method after the request finished, and there's no crash any more.
