Help with Native Crash

I am having this same crash on multiple iOS devices according to Performance Reporting. Can anyone please help me identify why it is crashing. Thanks.

Same problem here! Any solution?

 

The same issue here in u2018.2.20f1 as well only for iOS 12.x. Any luck?

 

Currently, there hasn't been any submitted reports of this issue.

If you could please submit a bug report with a sample project to reproduce the issue, we can investigate further.

 

Having the same crash, any solution for it?

Unity 2018.4.0f1

 

Is anyone else seeing this error currently? We're on 2018.2.6f1, and see this in XCode as a top Crash reported.
We are never able to repeat the error in internal tests.
