Hello @Michael_Condon ,
I have updated the SDK version to 5.4.54802.0124 (the latest one available at the moment).
The issue still reproduces according to steps.

Hey @s.nikitin,

Thank you for checking that.
This is only happening on iPad correct?
Do you have the MobileRTC app delegate calls in your AppDelegate? Like appWillTerminate defined in MobileRTC?

Thanks!

Hello @Michael_Condon ,
Thank you for the advise. After implementing the life cycle calls in the App Delegate the crash disappeared.
