4.0.3 works but 4.0.4 is broken for me

Auto-respone: if anyone is using xampp the quick way to fix this is open php.ini and uncomment:

extension=intl

Missing function:
// file: ./system/CodeIgniter/CodeIgniter.php

PHP Code:

/**
  * Handles some basic app and environment setup.
*/
public function initialize()
{
  // Set default locale on the server
  // John ADDED FOLLOWING CHECK BECAUSE STILL TO BE SET ON MY SYSTEM  
  if( function_exists('locale_set_default' ) ) :
    locale_set_default($this->config->defaultLocale ?? 'en');
  endif;

I removed the comment and it worked fine.
Thank you, John!
