I upgrade this module from 4.0 to 4.0.1 (which also required upgraded league/csv from 9.15 to 9.18) and it broke my site! I got “The website encountered an unexpected error. Try again later.”. I tried clearing the cache using drush but it still didn't work. So I downgraded back to 4.0 and league/csv to 9.15 and the site came back...phew!
The error log showed this error and backtrace:
Error: Class "Drupal\csv_serialization\EventSubscriber\CsvSubscriber" not found in Drupal\Component\DependencyInjection\Container->createService() (line 259 of /var/www/drupal/web/core/lib/Drupal/Component/DependencyInjection/Container.php).
