Still happening.

We also do not encounter this crash in iOS 15.0.1. It takes less than 10 seconds for the app to launch but in iOS 15.1 it always takes 23 seconds before it gets killed by the watchdog. All of our old builds since August crash on first launch in iOS 15.1 only.

Correction, the issue only happens with XCode 13.0 running in iOS Simulator 15.0. And I have not verified if the issue is also there when run in a real device. For XCode 12.5.1 running in iOS Simulator 14.5, it works fine.
