I experience iOS 15.1 crash on fresh install, first-time app launch, succeeding launch works fine. This is the watchdog termination but it only happens in iOS 15.1, tested in iOS 14.5 and it works fine.

Updated my environment recently to Big Sur and Xcode 12.5.1. I have an app that downloads pdf files and saves it externally to be viewed in the Files App. Everything works fine on real device but not in the simulator.
I observed that files in Documents folder of the iOS simulator(iOS 15.0) do not show up in the Files app anymore.
Is there any permission/hiccup here that I should be aware of?
