EntityBrowser - Drupal 9 - Error when configuring an entity browser views display

[joshua-graham-adelphi]

Hi Team,

A New Drupal View for the Entity Browser cannot be configured.

This resolved in https://www.drupal.org/project/entity_browser/issues/3154079 and dependabot update: #260
[requires 8.x-2.5 => 8.x-2.6 update]

The website encountered an unexpected error. Please try again later.
