    Are you using ECS and/or the Job system? I just got the same crash error on a friends PC and i'm using ECS and jobs heavily.

    No. I use "normal" code.

    ZwWaitForMultipleObjects is a window problem so it is irrelevant to my problem of crash in iOS.

    I had a similar issue and asked Unity for support. Apparently this error occurs when you have a NullReferenceException inside a coroutine. Not fun to debug unfortunately if you have many coroutines.
