Share Extension won't launch after upgrading to SDK 51

Everything was working on SDK 50. I upgraded to SDK 51 using Expo's instructions. The app itself works fine. When I try to launch the share extension, I now get this error:

I have tried:

clearing all caches (metro, pods, etc)
deleting all node_modules + yarn.lock and reinstalling everything
new builds

Note that I am in a monorepo but this has never caused issues before. I simply upgraded from SDK 50 to SDK 51, updating package versions and nothing else, and the issue started occurring.

I have tried launching the share extension on both the iOS simulator as well as my physical device, same issue occurs (debug mode and release mode fail).

Here are relevant files:

metro.config.js

// Learn more https://docs.expo.io/guides/customizing-metro
/**
 * @type {import('expo/metro-config')}
 */
// Sentry replacement
// const { getDefaultConfig } = require('expo/metro-config');
const { getSentryExpoConfig } = require('@sentry/react-native/metro');

const path = require('path');

const projectRoot = __dirname;
const workspaceRoot = path.resolve(__dirname, '../..');

// Sentry replacement
// const config = getDefaultConfig(projectRoot);
const config = getSentryExpoConfig(projectRoot);

config.watchFolders = [workspaceRoot];
config.resolver.nodeModulesPaths = [
  path.resolve(projectRoot, 'node_modules'),
  path.resolve(workspaceRoot, 'node_modules'),
];

config.transformer = { ...config.transformer, unstable_allowRequireContext: true };
// ! HAVE TO USE metro-minify-esbuild BC TERSER WAS BREAKING THE BUILD ENTIRELY!
config.transformer.minifierPath = require.resolve('metro-minify-esbuild');
config.transformer.minifierConfig = {
  drop: ['console'],
};

/**
 * Add support for share.js as a recognized extension to the Metro config.
 * This allows creating an index.share.js entry point for our iOS share extension
 */
config.transformer.getTransformOptions = () => ({
  resolver: {
    sourceExts: [...config.resolver.sourceExts, 'share.js'], // Add 'share.js' as a recognized extension
  },
});

module.exports = config;

index.share.js

// could be any component you want to use as the root component of your share extension's bundle
import { ShareExtension } from 'app/shareExtension';
import { AppRegistry } from 'react-native';

// IMPORTANT: the first argument to registerComponent, must be "shareExtension"
AppRegistry.registerComponent('shareExtension', () => ShareExtension);

index.js

// import 'expo-router/entry';

import { registerRootComponent } from 'expo';
import { ExpoRoot } from 'expo-router';

// Must be exported or Fast Refresh won't update the context
export function App() {
  const ctx = require.context('./app');
  return <ExpoRoot context={ctx} />;
}

registerRootComponent(App);
