CKEditor 5 implementation is wrong

Please release a CKEditor5 version that works already. It has been a year.

Applying this patch seems to get past the upgrade path issues I had when first trying to update to CKEditor5.
When implementing the buttons into a profile though I get errors when loading the editor on fields.

Background Color and Font Color buttons throw this error and do not allow the editor to load.

Taking the all of these buttons out of the profile allows the editor to load again.

Drupal 9.5.11
FireFox 126.0.1

I'm curious as to what the issue is that this change is intended to fix.

Upgrading to the latest release (2.0.0-beta4) seems to work with core 10.1.8.

@kerasai Thete is a way to create CKEditor 5 plugin structure when we do some changes to the plugin code we build though the webpack for that we need proper webpack and we found security issue with packages inside package.json are older while security audit, we have upgraded that. https://git.drupalcode.org/project/ckeditor_font/-/merge_requests/20/dif...

Last one the current plugin missing the color picker implementation you can see below screenshot
