Problem/Motivation

After updating core from 9.4 to 10.1, pages that use CKEditor give a WSOD with the following error.

Drupal\Component\Plugin\Exception\PluginException: Plugin (ckeditor) instance class "Drupal\ckeditor\Plugin\Editor\CKEditor" does not exist. in Drupal\Component\Plugin\Factory\DefaultFactory::getPluginClass() (line 97 of core/lib/Drupal/Component/Plugin/Factory/DefaultFactory.php).

Steps to reproduce

Use CKEditor 4 module with core 9.5
Update core to 10.1
Go to any page that would use the CKEditor plugin, see error.

composer.json and composer.lock attached.

Solution
Restarting my development server fixed the problem. Got the idea from this other similar issue.
