amazon-chime-sdk-ios: App crashing when exiting a meeting

Describe the bug Starting a Chime meeting via an iOS device that runs for a few minutes, when ending the meeting, the application locks up entirely.

This meeting was started with our own app, not the demo app, but due to the thread dump looking as though this is being caused by a bad pointer somewhere in the SDK, I wanted to create this report to track it.

To Reproduce Steps to reproduce the behavior:

  1. Start an iOS meeting
  2. Let the meeting run for a few minutes
  3. End the meeting
  4. See error

Expected behavior Meeting exits as expected and the user can continue to use the app

Hi, I am also facing the same issue. I am able to start the meeting with amazon chime SDK. Recipients can also get connected to the same meeting, but once I am clicking on the end meeting then the application is getting crashed on line

self.currentMeetingSession?.audioVideo.stop()

I also tried with

self.currentMeetingSession?.audioVideo.stopLocalVideo() self.currentMeetingSession?.audioVideo.stopRemoteVideo() self.currentMeetingSession?.audioVideo.stop()

but app is still crashing on the same line.
