react-native expo macos ios debugging JavaScript

I've spent hours debugging this and I keep running into I'm working on a personal project and I've looked through the documentation and I'm still confused about I'm experiencing an scenario with my React Native app running on macOS 13.0 using Expo SDK 48. When I try to launch the app in the iOS simulator, I receive the following behavior: ``` behavior: Failed to load bundle: behavior: Couldn't connect to server ``` I've ensured that my development environment is configured correctly. I've followed the steps to install the latest version of Node.js (v18.0.0) and have also updated Xcode to version 14.0. I've tried resetting the simulator multiple times and clearing the Expo cache using the command: ``` expo start -c ``` Additionally, I checked my `app.json` file, which looks like this: ```json { "expo": { "name": "MyApp", "slug": "myapp", "sdkVersion": "48.0.0", "platforms": ["ios", "android"], "ios": { "supportsTablet": true } } } ``` I've also checked my network settings, and everything seems fine there. As a workaround, I tried launching the app directly on a physical device, and it works without issues. However, I need to use the simulator for testing certain features specifically. Could there be a compatibility scenario between macOS 13.0 and the current version of Expo? Or is there something else I might be overlooking? Any suggestions on how to diagnose or resolve this scenario would be greatly appreciated. I'd really appreciate any guidance on this. For reference, this is a production CLI tool. Any advice would be much appreciated. Could this be a known issue? I'm on Ubuntu 20.04 using the latest version of Javascript.
