Cannot edit, delete or disable Webform Navigation handler from Emails/Handlers page

Problem/Motivation

Ajax errors in console:

https://pacsd9.ddev.site/admin/structure/webform/manage/WEBFORM_ID/handl... returns a 404

Going to that URL shows:

Symfony\Component\HttpKernel\Exception\NotFoundHttpException: Only 1 instance is permitted in Drupal\webform\Form\WebformHandlerFormBase->buildForm() (line 115 of modules/contrib/webform/src/Form/WebformHandlerFormBase.php).

Steps to reproduce

Add the Webform Navigation handler to a webform at /admin/structure/webform/manage/WEBFORM_ID/handlers

After adding, try to click on "Edit" or "Delete" or "Disable" in the handler's operations. Nothing happens.
