Ionic Android App stuck on white screen after upgrading to Angular 12. Error: goog.getLocale is not a function

I recently tried upgrading Angular 11 to 12 in my Ionic App. It all went well, and the app is running with no errors in the browser. However, when I tried to run it on an Android phone, after the splash-screen disappears, the app gets stuck in a white screen.

I tried using chrone://inspect tool and see if I get any errors and this showed up:

enter image description here

I also get the same error on the Android Logcat: E/Capacitor/Console: File: http://localhost/vendor-es2015.js - Line 15729 - Msg: ERROR TypeError: goog.getLocale is not a function

I tried adding timeout to the splash-screen, updating libraries, deleting node_modules and reinstalling them, but nothing worked. I can't find much info on the web about this error.

Can anyone tell me what this error means or why is the app stuck here? It works well if I go back to Angular 11.

    as a temporary fix avoid to call the getGlobalLocale(). Add this to your index.html

    <script>
  var ngI18nClosureMode = false;
</script>

    same here updating from [email protected] to @12.2.

    meanwhile try to update to ^12.1
