Hello @subhronil_blusmart, thank you for sharing a crash log. Our engineering teams need to investigate this issue, as resolution may involve changes to Apple's software. I'd greatly appreciate it if you could open a bug report, include a sysdiagnose if possible, and post the FB number here once you do. Bug Reporting: How and Why? has tips on creating your bug report.
