Drupal 11 appears to be incompatible with Entity Reference Hierarchy 3.x and 5.x. An attempt to add a field to a content type in each of these two versions throws the following error:
AssertionError: "Reference" must be defined in MODULE_NAME.field_type_categories.yml in assert() (line 183 of /var/www/html/web/core/lib/Drupal/Core/Field/FieldTypePluginManager.php).
The error does not occur with Drupal 10.3.

Thanks, seems like we're missing something from the yml in that file then
