App won't load after upgrading to RN 0.62 - react-native

Question

After upgrading to RN 0.62.2 from 0.61.3 using the RN tools for upgrading, updating pod (even had to modify a line in podspec following this to make it work : CocoaPods could not find compatible versions for pod "ReactCommon/jscallinvoker":)
My app build but get stuck on the splashscreen. It's working well on RN 0.61.3
This is what i have in the metro console :
[Wed Apr 22 2020 18:22:25.108] WARN Require cycle: node_modules/react-native-af-video-player/components/index.js -> node_modules/react-native-af-video-player/components/TopBar.js -> node_modules/react-native-af-video-player/components/index.js
Require cycles are allowed, but can result in uninitialized values. Consider refactoring to remove the need for a cycle.

Anyone running in the same issue and any idea on how i can debug that ?
I tried deleting node modules and reinstall everything it does not solve the problem.
When i console log from my index.js i have nothing.
EDIT : This is the full error i have in Xcode :

Answer 1

Finally after some search, i had to disable page per page all my component to see what was the cause of the problem. It appear that this package i was using : react-native-confirmation-code-fieldneeded to be updated ! (the maintainer was aware of the problem with RN 0.62 and updated it, thanks to him !
I also needed to update reac-native-firebase if someone run into the same problem and use those modules.
The best way to debug is to do bit by bit by removing everything and added all the piece back together component per component when log in console are not clear
