Description

When updating to Laravel 11, if you remove the app config file but leave the sanctum file the call to Sanctum::currentApplicationUrlWithPort() will cause the underlying fetch of config('app.url') will result in a null value being returned.

So far I have found 2 workarounds:

1. Remove the sanctum.php or at least remove the definition of stateful from the file.
2. Make sure to define the SANCTUM_STATEFUL_DOMAINS in the env file.

Steps To Reproduce

1. Upgrade from Laravel 10 to Laravel 11.
2. Remove the app.php config file (If you use Laravel Shift, this is done for you)
3. Try opening the app using stateful domains without defining SANCTUM_STATEFUL_DOMAINS in the .env file

if you remove the app config file

We don't officially support removing this file. Just leave it in.
