I developed react app and deployed it through to GitHub pages but it shows this empty screen i cant understand this do you know what is wrong?

{
  "homepage": "https://mohamedsha0919.github.io/hungrybitess",
  "scripts": {
    "deploy": "gh-pages -d build",
    "predeploy": "npm run build"
  }
}

Everything works well locally, but does not work in github pages. Hope that anyone can help! Thanks!
