Upgrading version

0.63.4

Description

Hi, I'm attempting to upgrade my react native project to version 0.63.4 from version 0.61.5.

I managed to get the build working by following the dedicated upgrade helper for my migration (https://react-native-community.github.io/upgrade-helper/?from=0.61.5&to=0.63.4)

I however still have one major issue, when running the app on the Simulator, once the bundle work finished I'm instantly getting an RCTFatal error, which doesn't really give me any indication as to where the problem comes from.

Here is a copy of the error shown on the iOS simulator.

RCTFatal
__28-[RCTCxxBridge handleError:]_block_invoke
_dispatch_call_block_and_release
_dispatch_client_callout
_dispatch_main_queue_callback_4CF
__CFRUNLOOP_IS_SERVICING_THE_MAIN_DISPATCH_QUEUE__
__CFRunLoopRun
CFRunLoopRunSpecific
GSEventRunModal
-[UIApplication _run]
UIApplicationMain
main
start
0x0

Does anyone has ever seen such an error? Am I missing something?
Is there anything I can do to get more debug/error info?

(Note: I'm familiar with iOS development but I'm more from low-level language background and since the beginning of my career JS and Android development so I must I am a bit of a newbie regarding xCode, I know basic but not necessarily all the caveats when going about debugging).

Thanks for your help,

Antoine Mace
