App Icon for ios standalone gone

I am having an issue with my app icon since around christmas.
I did not change any of my assets or any code in app.json but suddenly the App Icon just did not show up with the new IPA. No error is thrown in the building process.

Edit: The project at the expo website shows the icon correctly

I tried removing the Icon and reimporting it to the assets folder but that didn’t do any difference.

Here is my app.json:

{
  "expo": {
    "name": "xxx",
    "slug": "xxx",
    "privacy": "unlisted",
    "sdkVersion": "34.0.0",
    "platforms": [
      "ios",
      "android",
      "web"
    ],
    "version": "1.0.14",
    "orientation": "portrait",
    "icon": "./assets/images/icon.png",
    "splash": {
      "image": "./assets/images/splash.png",
      "resizeMode": "contain",
      "backgroundColor": "#fff"
    },
    "updates": {
      "fallbackToCacheTimeout": 0
    },
    "assetBundlePatterns": [
       "**/*"
     ],
    "ios": {
      "supportsTablet": true,
      "bundleIdentifier": "xxx",
    },
    "android": {
      "package": "xxx",
      "versionCode": 7,
      "permissions": [
        "CAMERA",
        "READ_INTERNAL_STORAGE",
        "WRITE_INTERNAL_STORAGE",
        "READ_EXTERNAL_STORAGE",
        "WRITE_EXTERNAL_STORAGE"
      ],
    },
    "androidStatusBar": {
      "backgroundColor": "#000000"
    },
    "description": ""
  }
}

Please run expo diagnostics and paste the log that’s printed out along with your question or issue!
