When adding a link into a rich text field (wysiwyg) (see images bellow) and searching for a keyword the throbber icon keeps spinning and that's it.
I looked at the error logs and found the following, this was working recently, no idea what happened.
Uncaught PHP Exception Drupal\Component\Plugin\Exception\PluginNotFoundException: "The "entity:media" plugin does not exist. Valid plugin IDs for Drupal\linkit\MatcherManager are: entity:contact_form, email, entity:contact_message, entity:feeds_feed, entity:node, entity:scheduled_update, entity:taxonomy_term, entity:user, entity:file, front_page"
If anyone has an idea what happened? Drupal 8.7.3
