CRNA build:android issues

Question

I am trying to build an APK file for my CRNA project, using expo. The first issue is, it tries to build iOS every time. Why is it building iOS when I used exp build:android? Second, iOS only succeeds in building occasionally. It usually hangs at 0%.

The output is below:

> exp build:android

And then it hanngs indefinitely. Has anyone came across any of these issues and have any advice?

My app.json is below

{
  "expo": {
    "sdkVersion": "27.0.0",
    "icon": "./test-icon.png",
    "entryPoint": "./AppEntry.js",
    "ignoreNodeModulesValidation": true,
    "packagerOpts": {
      "config": "rn-cli.config.js",
      "projectRoots": ""
    },
    "android":{
      "package": "expo.android.package",
    },
    "ios":{
      "bundleIdentifier": "expo.ios.package",
    },
  },
  "privacy": "unlisted",
  "platforms": ["ios", "android"],
  "version": "1.0.0",
  "orientation": "portrait"
}

expo version: 55.0.4

react-native version: 0.55.4
