Why create function in RegisterController is not working in laravel

I am new to Laravel. I am using registerController in Laravel to create users . Users data are stored in Users table.

What I have tried is :

    @extends('adminlte::auth.auth-page', ['auth_type' => 'register'])
    
    @php( $login_url = View::getSection('login_url') ?? config('adminlte.login_url', 'login') )
    @php( $register_url = View::getSection('register_url') ?? config('adminlte.register_url', 'register') )
    
    @if (config('adminlte.use_route_url', false))
        @php( $login_url = $login_url ? route($login_url) : '' )
        @php( $register_url = $register_url ? route($register_url) : '' )
    @else
        @php( $login_url = $login_url ? url($login_url) : '' )
        @php( $register_url = $register_url ? url($register_url) : '' )
    @endif
    
    @section('auth_header', __('adminlte::adminlte.register_message'))
    
    @section('auth_body')<!-- comment -->
    <?php $roles = DB::table('roles')->where('id','>',1)->get(); ?>
    <div class="login-form">
        <div class="container">
            <div class="row ">
                <div class="register-box">
