After installing module (3.3.11) on Drupal 11.0.10, and try to "Create new field" on any content type I got error
"Exception: Invalid field category for field type: "entity_reference_hierarchy", category must be the ID of a defined field category, got "Reference". in Drupal\field_ui\Form\FieldStorageAddForm->processFieldDefinitions() (line 136 of /app/docroot/core/modules/field_ui/src/Form/FieldStorageAddForm.php)."
1. Install module
2. Go to "Manage fields" (any content type)
3. Click on "Create new field" you got WOS
NOTE: Default message in watchdog was
"TypeError: Cannot access offset of type Drupal\Core\StringTranslation\TranslatableMarkup in isset or empty in Drupal\Core\Plugin\DefaultPluginManager->doGetDefinition() (line 45 of /app/docroot/core/lib/Drupal/Component/Plugin/Discovery/DiscoveryTrait.php)."
But after applying patch from

Code (module)
I think the problem is already fixed in current default 3.x branch.
See the definition in the source code of the mentioned field type. Category is set there as ID, not as translatable string.
