Steps to Reproduce
Our iOS app in production has been working with no issues. However, a few days ago, my own device's installation of our production app just so happened to experience a crash after cold launching the app (a split second after the bundle fully loaded). This crash was captured by our Fabric Crashlytics. No other instances of this crash has been reported by our customers -- this was the only case we saw, and we could not reproduce it.
My device details:
iPhone 8
iOS 11.3.1
Crashlytics combined two crash outputs within this crash issue -- outputs are provided below. (I've replaced our app's name with OURAPP).
