This code seems to be duplicated across your project.

      if ($entity instanceof TranslatableInterface && isset($args['language']) && $args['language'] != $entity->language()->getId()) {

The class Drupal\Core\TypedData\TranslatableInterface does not exist. Did you forget a USE statement, or did you not list all dependencies?

        $entity = $entity->getTranslation($args['language']);
      }

      yield new CacheableValue($entity, [$access]);
    }
    else {
      // If the entity exists but we do not grant access to it, we still want
      // to have it's cache metadata in the output because future changes to
      // the entity might affect its visibility for the user.
