New fresh install get error

[aliqasemzadeh]

Hi
When I install composer install
I get the following error:

> @php artisan package:discover --ansi
In app.php line 158:
Call to undefined method Illuminate\Support\ServiceProvider::defaultProviders()
Script @php artisan package:discover --ansi handling the post-autoload-dump event returned with error code 1

Why do I get this error?
My php version is 8.1

Looks like framework changes #46786 haven't been published yet, but skeleton laravel/laravel#6159 does.
