@Anand_Vyass, Appreciate your swift response! Could you please clarify if you’re utilizing iOS or React Native? I noticed React Native was referenced earlier. ---

Thank you, IT was prompt response from you as well. IT is purely native iOS. I Upgraded Zoom Meeting SDK to latest 5.17.11 in my iOS App, Xcode 15.3 We Supported iOS 15.0 or later Previous version of Zoom which was running perfectly - Zoom SDK 5.16.5. **Which iOS Meeting SDK version?** 5.17.11 1. I am just trying to Join or Start meeting 2. Able to Join/Start meeting successfully 3. After 2-4 seconds app crashes, and if I simply replace the sdk back to 5.16.5 it works just fine as normal. ---

Hi @Anand_Vyass , Can you share your start meeting function? Also try to call the start meeting on main thread, e.g. func startMeeting(){ DispatchQueue.main.async { **let** meetingService = MobileRTC.shared().getMeetingService() … } } ---
