I have an app that launches fine on device and the simulator from Xcode 11.2 on macOS 10.15.1.
I just upgraded to Xcode 11.3 and macOS 10.15.2. The app still launches fine from Xcode to a device. When launching on the simulator, it immediately crashes with "Message from debugger: Terminated due to signal 6". This happens with 13.3 and 11.4 simulated devices.
Stack trace below. It doesn't look to me like it's even getting into the app code. Anyone else seeing this?
