i get an error when integrating ckeditor in a nextjs app

Question

I am trying to integrate CKeditor5, using a custom build (built using online builder), which when testing with a regular create-react-app, worked, but failing when i use the same custom build in my next.app, it prints a very heavy error in the console during bundling, and the whole app slows down, moreover not even working. i completely failed to figure out where and how to start troubleshooting. below is my ckeditor component, the package.json file, and part of the printed error

the ckeditor react component

import React, { Component } from 'react';
import Editor from 'ckeditor5-custom-build/build/ckeditor';
import { CKEditor } from '@ckeditor/ckeditor5-react'

class JEditor extends Component {
    constructor(props) {
      super(props);
      this.state = {
        content: this.props.data,
      };
      this.EditorConfiguration = {
        toolbar: this.props.ToolBar,
      
        mention: {
          feeds: [
            {
              marker: "@",
              feed: this.props.Tools,
              minimumCharacters: 0,
            },
          ],
        },
        placeholder: this.props.placeholder,
      };
    }
  
    render() {
      return (
        <div className="App">
          <br />
          <CKEditor
            editor={Editor}
            config={this.EditorConfiguration}
            data={this.content}
            onChange={(editor) => {
              const editorData = editor.getData();
              this.props.handleData(editorData);
            }}
          />
        </div>
      );
    }
  }



export default JEditor;
