Unity Cloud Diagnostics is reporting a significant number of Native Crash - __pthread_kill end-user crashes on iOS, and we don’t have much in the way of leads as far as what the reproduction steps are, or what we can even investigate.
Info on this particular instance of the crash:
Editor Version: 2018.4.6f1
OS: iOS 13.1.3
Device: iPhone9,3
And here is the stack trace that we are given, and on which hopefully someone can shed some light.
