❓ Possible solution

Both packages are latest releases, and I'm able to repro without "@ckeditor/ckeditor5-angular" at all, simply importing anything from "ckeditor5"; I have also tried clearing npm cache and reinstalling hte packages.

The issue lacks the feedback we asked for two weeks. Hence, we've marked it as stale and will close it in 30 days. We understand it may still be relevant, so if you're interested in the solution, leave a comment or reaction under this issue.

Thank you, I unfortunately was assigned different tasks this last week, but I'm back on evaluating CKEditor. I am still attempting to build a base case that reproduces. Our ng project was originally an old angular release and has been upgraded to ng 14 to support the same ts version ckeditor uses. We have some base modules that I have added the ckeditor module to as an import and export.

Unable to get a reproduction on a simple base ng 14, but have a repro in our production project without even using the ng module component. Simply installing "ckeditor5": "42.0.2", then in a component simply have

import { ClassicEditor } from "ckeditor5"; ... public Editor = ClassicEditor;

Nothing else, and this throws the error on app initialization

Updating to ckeditor5 43 seems to have bypassed this issue.
