Android DeadSystemException

Currently we are experiencing a DeadSystemException in our HockeyApp crash reporting. It occures on Android 7.0 and Android 7.1. We don't experience this exception in previous version of our application (they are currently both used by users), so I guess this exception is caused by some code change. But stack trace is not wery helpful for this. Any idea? Thanks for any sugestion.

Stack trace from HockeyApp:
