CKeditor 5 plugincollection Error in console

Nothing mentioned in the issue indicates this is specific to the ckeditor5_dev module. Does this issue only happen if the ckeditor5_dev is enabled?

Hi,

I think its core CKeditor 5 module installed in website. Sorry for mentioning the wrong version. Now i have attached the screenshots to understand the issue.
For that, we have created the 'Test HTML' for using the CKeditor 5 module. Once it is selected in Text format in content, showing console error.

Drupal version : 10.2.2

Thanks.

I have also been struggling with this issue on my Full HMTM editing profile. My Basic HTML is fine.

It happened after upgrading to CKEditor 5 in Drupal 10 from CKEditor 4 in Drupal 9.

For me, this involved upgrading the Anchor Link module from CKEditor 4 to a CKEditor 5 version.

I found that the library for Anchor link was not loading and throwing an error that basically crashed the JS interpreter and stopped all of the other JS from running. I would check to make sure that any additional plugins that your using on the text editing profile that is causing issues are not having conflicts.

Cheers,
Andrew

Thanks @awasson I had this same issue -- and indeed, I had also not installed the library. Once I got that in it started working again.
