You can show the output of the following commands:

php artisan route:list

and

php artisan tinker
>>> config('platform.domain');
>>> config('platform.prefix');

This is very strange, as you see in the user rights the specified value goes as true.

I still think that this is because of the update of the model of the User, and more precisely because of this line:

    /**
     * The attributes that should be cast to native types.
     *
     * @var array
     */
    protected $casts = [
        'email_verified_at' => 'datetime',
    ];

Because it replaces the base value:

    /**
     * @var array
     */
    protected $casts = [
        'permissions' => 'array',
    ];

Please add it now manually to your model.
