I have this problem. When I compile an application and run the command ionic cordova prepare android i see this error:

```auto
Error: Unknown argument: platform [ERROR] An error occurred while running subprocess ng. ng.cmd run app:ionic-cordova-build --platform=android exited with exit code 1. Re-running this command with the --verbose flag may provide more information.

My Config: Angular CLI: 14.0.2 Node: 16.13.0 Package Manager: npm 8.1.0 OS: win32 x64 

If i lunch the same command with this config: 
Angular CLI: 13.0.4 Node: 16.13.0 Package Manager: npm 8.1.0 OS: win32 x64 
the project work correctly
```

Two options:

1. Update Ionic to that Version
2. Don’t update to Angular 14 😃

You definitively should update to Ionic 6, if you use Angular 14 or not. Check the guide here: [Upgrading to Ionic 6 | Ionic Documentation](https://ionicframework.com/docs/intro/upgrading-to-ionic-6)
