User Story or Problem Statement

We are getting an error when trying to navigate to /admin/structure/views.

Drupal\Core\Entity\EntityMalformedException: The "view" entity cannot have a URI as it does not have an ID in Drupal\Core\Entity\EntityBase->toUrl() (line 161 of core/lib/Drupal/Core/Entity/EntityBase.php).

This seems to be caused by a the danse.user.notications view. I have tried removing it using config import and get and error. I have also tried placing the yaml form the config file int he module config in the config.sync file and updating it but get an error:
Unexpected error during import with operation update for views.view.danse_user_notifications: Attempt to update non-existing entity 'danse_user_notifications'.

Description or Additional Context

We aren't using the danse module anymore. Recommend resolution to remove it using the following tickets from the backlog.

• Write a script to delete all danse_event entities. #14125
• Disable danse_content_moderation and remove from codebase. #14124
• Remove DANSE and whatever else we did there. #13567

Remove view using:
drush eval "\Drupal::service('config.factory')->getEditable('views.view.danse_user_notifications')->delete();"

Steps for Implementation

This will require two PRs, the first is to remove the broken view and disable the DANSE modules. The second is to remove the DANSE modules from the code base.

Acceptance Criteria

• Disable and remove DANSE modules
• Remove broken danse_user_notifications view
• Remove DANSE modules from the code base
