OpenAI CKEditor integration compatibility issue with Drupal 10.3

I can confirm I also have this error with OpenAI CKEditor integration Module enabled. As soon as the module is disabled the CKEditor displays as expected. Prior to disabling the module the body filed on my content type would not display. See below screenshot

Updating the title of this issue and moving priority to Major as it makes the body field unusable.

The merge request has a fix, though this may cause problems with backward compatibility. This is a similar issue to 🐛 CKEditor 5 41.3.1 (Drupal 10.3 beta) breaking change Fixed ; we may need to do something like the fix in this issue to resolve the backward compatibility problem.
