Drupal 9 Compatibility - Symfony Error

Is dataprocessor compatible with Drupal 9?

When I try to install it on a D9 instance, I get the following apache log error: Uncaught PHP Exception Error: "Class "Symfony\\Component\\EventDispatcher\\Event" not found" at /var/www/example.org/web/sites/default/files/civicrm/ext/dataprocessor/Civi/DataProcessor/Event/ConfigContainerBuilderEvent.php line 12
