Invalid Plugin Definition Exception the taxonomy term entity type did not specify a inline_form handler in Drupal 10

Thu, Dec 14, 2023

• Drupal\Component\Plugin\Exception\InvalidPluginDefinitionException: The “taxonomy_term” entity type did not specify a inline_form handler. in Drupal\Core\Entity\EntityTypeManager->getHandler() (line 256 of core/lib/Drupal/Core/Entity/EntityTypeManager.php).

This fatal PHP error occurred on trying to edit a node.

… and a second cache reload (or heck, maybe only the page reload) fixed it.

Who knows.
