Failed to open stream: No such file or directory when upload it to shared hosting.

HI, I have a problem uploading the files in shared hosting. I edited the index.php in the that will be redirected to bootstrap, storage and vendor, however I always get error "Warning: require(/home/oabjsoar/public_html/cws/vendor/composer/../symfony/deprecation-contracts/function.php): Failed to open stream: No such file or directory in /home/oabjsoar/public_html/cws/vendor/composer/autoload_real.php on line 71" Anyone can help me?

Here is the code for the index.php

<?php

use Illuminate\Contracts\Http\Kernel;
use Illuminate\Http\Request;

define('LARAVEL_START', microtime(true));

/*
|--------------------------------------------------------------------------
| Check If The Application Is Under Maintenance
|--------------------------------------------------------------------------
|
| If the application is in maintenance / demo mode via the "down" command
| we will load this file so that any pre-rendered content can be shown
| instead of starting the framework, which could cause an exception.
|
*/

if (file_exists($maintenance = __DIR__.'/cws/storage/framework/maintenance.php')) {
    require $maintenance;
}

/*
|--------------------------------------------------------------------------
| Register The Auto Loader
|--------------------------------------------------------------------------
|
| Composer provides a convenient, automatically generated class loader for
| this application. We just need to utilize it! We'll simply require it
| into the script here so we don't need to manually load our classes.
|
*/

require __DIR__.'/cws/vendor/autoload.php';

/*
|--------------------------------------------------------------------------
| Run The Application
|--------------------------------------------------------------------------
|
| Once we have the application, we can handle the incoming request using
| the application's HTTP kernel. Then, we will send the response back
| to this client's browser, allowing them to enjoy our application.
|
*/

$app = require_once __DIR__.'/cws/bootstrap/app.php';

$kernel = $app->make(Kernel::class);

$response = $kernel->handle(
    $request = Request::capture()
)->send();

Now here is my file directory hierarchy in the shared hosting under public HTML

-public html
--bootstrap
--css
--cws(main laravel folder)
--datatables
--dist
--fonts
--js
--toastr
--.htaccess
--error_log
--favicon.ico
--index.php
--mix-manifest.json
--robots.txt
