Example app crashes on iOS 15.4, emulator only

Describe the bug
The app crashes under very specific conditions:

• emulator-only (it worked fine on my iPhone 13 Pro, even after upgrading to 15.4)
• iOS 15.4 (works fine on emulator for 14.2)
• release vs debug build : crashes in both modes
• I first tested under tag 8.5.0 and also on main (crashes on both)

To Reproduce

• follow steps to run example (git clone…, git checkout 8.5.0, cd example, yarn ios)
• select Map > Show Map
• Observe crash (crashes very consistently for me, perhaps 9/10 times)

Expected behavior
No crash.

Actual behavior
I get the crash report below.

Versions (please complete the following information):

• Platform: iOS
• Platform OS: 15.4
• Device: tested on 12 and 13
• Emulator/ Simulator: yes, emulator only
• Dev OS: OSX 12.2.1
• react-native-mapbox-gl Version 8.5.0 and main
• Mapbox GL version for master: defaults for 8.5.0 / main
• React Native Version 0.66.0

I can report that I am seeing the same thing after my simulators updated to 15.4 this morning, it will immediately crash on startup.

The only thing I have to add is that if I take out references to <MapboxGL.Camera ... /> it will not crash on startup. And I can even add it back in via hot reloading and the app will function just fine, so maybe there is a race condition somewhere?

Hope this helps.
