React native upgrade from 0.70.5 to 0.72.6 gone wrong

I am using the ignite boilerplate for my React Native app and was forced to upgrade react-native to 0.72.6 from 0.70.5 because I upgraded to Xcode 15 (didn’t know any better). Now, after finally getting the build to succeed, I have run into a strange error.

Unhandled JS Exception: Value is an object, expected an Object
Error: Value is an object, expected an Object

I tried npx react-native upgrade and then took the help of https://react-native-community.github.io/upgrade-helper/?from=0.70.5&to=0.72.6 to make relevant changes to successfully get the app to build in Xcode. But the nightmare didn’t end there.

There is no stack trace on the error, and the Xcode logs look like this:

And this is what I see on the simulator:

Any ideas to debug this? I’ve already wasted 2 days. I’m new to RN and Xcode.

Edit: If I click on Reload on the error bottom sheet in simulator, the app pauses here in the debugger:

{
  self.moduleName = @"App";
  // You can add your custom initial props in the dictionary below.
  // They will be passed down to the ViewController used by React Native.
  self.initialProps = @{};

  return [super application:application didFinishLaunchingWithOptions:launchOptions];
}
