Hi,
are you using AB testing for in-app messages by any chance?
There is an open issue with AB testing for in-app messages. Control group of AB tests has null payload and results in this crash.
My advice is to disable AB testing or set it up so that there is 0% in the control group.

Hi.
Yes, i was created control groups on 50% user show in-app massage.

The issue around in-app messages control groups is currently being worked on. We'll ping you once there is a solution.
For now, please don't AB test in-app messages.
