React Native Bundler Bug?

Description

I'm not sure what's going on. I spent the afternoon trying to figure out how to run a new React Native project at version 0.78.0. I simply created a new project using the following command:

npx @react-native-community/cli@17.0.0 init AwesomeProject --version 0.78.0

The project was created, and I was able to build it successfully. However, as soon as I ran the Metro bundler, the app displayed a black screen. I had to manually close the app and reopen it for anything to appear.

Steps to reproduce

1. First init a new project with npx @react-native-community/cli@17.0.0 init AwesomeProject --version 0.78.0
2. Run npm run android && npm run start
3. Await it to build, as soon as the app run close it, and open again manually.

React Native Version

0.78.0

Reproduisez le problème en créant React Native 0.78.0 avec la commande CLI indiquée, puis exécutez npm run android  npm run start dans l’environnement Android signalé. Commencez par retracer le chemin de démarrage du Metro bundler et comparez le premier lancement avec la réouverture de l’application. C’est terminé lorsqu’une application nouvellement compilée s’affiche normalement lors de son premier lancement sans devoir la fermer et la rouvrir manuellement.
