iOS: app crashes when leaving a meeting (meeting sdk)

Meeting SDK iOS
1

Description
Hi! We updated the zoom ios SDK on our app to latest but we encountered an issue (which we can’t really determine what causes the crash). The app crashes after ending the video meeting session.

Which iOS Meeting SDK version?
iOS SDK: v5.15.5.9353

Smartphone (please complete the following information):

  • Device: iPad Pro (2nd gen)
  • OS: iOS 16.6

Additional context

  • We developed our app using Flutter.
  • We integrated the zoom ios sdk using native ios implementation in Flutter
  • Our previous sdk version is: v5.11.3.4099 (nothing wrong with this one; can join and end meeting)
  • We used custom meeting UI

Please help. Thank you!

Please disregard this topic as issue was already resolved. It was not zoom sdk related. Apologies.
