Issue when using Laravel 9 on CPanel triggers 500 error.

[GreeK]

Hello everyone, I'm working with Laravel 9 and I uploaded it to hosting with cPanel, but I'm getting a 500 error. Here is the log:

[18-May-2024 22:42:53 UTC] PHP Warning: require(/home/oacj2024/moliflu/vendor/composer/../symfony/polyfill-mbstring/bootstrap.php): Failed to open stream: No such file or directory in /home/oacj2024/moliflu/vendor/composer/autoload_real.php on line 41

I'm not sure what could be causing this issue. I have properly configured the index.
