The reason from your crash is in the crash log:
exhausted real (wall clock) time allowance of 19.95 seconds
Your app is taking too long to launch (or to be precise, to call didFinishLaunching from the app delegate).
From the stack trace it looks like this is a React Native app so maybe in your RN code you are performing an operation that leads to a never ending loop, maybe performing a (blocking) networking call on the main thread? Have you tested your app without any connectivity?
