When a UseBB user with a username that already exists on the Drupal installation is imported, the import fails without a visible error after the batch, but with the following error in the database log:

Drupal\Core\Database\IntegrityConstraintViolationException: SQLSTATE[23000]: Integrity constraint violation: 1062 Duplicate entry '[user]-en' for key 'user__name': INSERT INTO {users_field_data} ...

Importing users with a preexisting username should rename the usernames using the dedupe_entity process plugin.
