I am experiencing a device specific issue after the latest meeting Sdk upgrade(version 5.16.1).  
particularly i have issue with the Redmi note 9 pro model. The app Crashed when i am trying to join the meeting.

The fatal exception my debugger showing is following,

Hey, @ociuzteam, Thanks for posting in the Zoom Developer Forum. Can you share if this only started happening with the latest meeting Sdk upgrade(version 5.16.1)? Was the same code working prior to this happening?
