If Joomla did not re-create autoload_psr4.php on the next page load you may have a permissions problem. Run the Forum Post Assistant (red box above) and post the public results here.
Also, edit configuration.php and set $debug = true; and $error_reporting = 'maximum'; (change permissions to 644 first). That should give you a stack trace when you reload the site. Post the stack trace here.
