iOS -> App hanging for at least 2000 ms. App Hanging <compiler-generated> thunk for closure

[DragomirAndrei19]

Describe the bug Sentry reports that for some iOS users, the app hangs for 2000ms or more due to this library

Code snippet

import MyApp from "MyApp";
import React, { useEffect } from "react";
import "./src/localization/i18n";
import { GestureHandlerRootView } from "react-native-gesture-handler";
import { SafeAreaProvider } from "react-native-safe-area-context";
import * as Sentry from "@sentry/react-native";
import APIConstants from "models/APIConstants/API_CONSTANTS";

export const navigationIntegration = Sentry.reactNavigationIntegration({
  enableTimeToInitialDisplay: true,
});

export const IGNORE_SENTRY_PASSPHRASE: string = "IGNORE SENTRY PASSPHRASE";

Sentry.init({
  dsn: APIConstants.SENTRY_URL,
  enabled: SENTRY_URL && !__DEV__ ? true : false,
  // spotlight: __DEV__,
  tracesSampleRate: 1.0,
  integrations: [navigationIntegration],
  sendDefaultPii: true,
  ignoreErrors: [IGNORE_SENTRY_PASSPHRASE],

});
import { GoogleSignin } from "@react-native-google-signin/google-signin";
import { IOS_AUTH_CLIENTID, SENTRY_URL, WEB_CLIENT_AUTH_ID } from "@env";
import { useThemeStore } from "zustand/themes/useThemeStore";
import { KeyboardProvider } from "react-native-keyboard-controller";

const App = () => {
  const backgroundColor = useThemeStore((state) => state.colors.background);

  useEffect(() => {
    configureGoogleSignin();
  }, []);

  const configureGoogleSignin = () => {
    GoogleSignin.configure({
      webClientId: WEB_CLIENT_AUTH_ID,
      iosClientId: IOS_AUTH_CLIENTID,
    });
  };

  return (
    <SafeAreaProvider style={{ flex: 1, backgroundColor: backgroundColor }}>
      <KeyboardProvider>
        <GestureHandlerRootView>
          <MyApp />
        </GestureHandlerRootView>
      </KeyboardProvider>
    </SafeAreaProvider>
  );
};

export default Sentry.wrap(App);

Expected behavior No app hangs.
