Error after upgrading to the latest version

Marked version:
13.0.1 (the previous version was 0.7.0)

Describe the bug
After upgrading the dependency from v0.7.0 to v13.0.1 and building my app I get this error:

[ ERROR ]  Rollup: Plugin Error: node_modules/marked/lib/marked.umd.js:253:15
           Unexpected token (253:15) in
           /home/public/src/Adevinta/Privacy-Broker/privacy-console/node_modules/marked/lib/marked.umd.js
           (plugin: commonjs, transform)

    L252:  class _Tokenizer {
    L253:      options;
    L254:      rules; // set by the lexer

[ ERROR ]  ENOENT: no such file or directory, open
           '/home/public/src/Adevinta/Privacy-Broker/privacy-console/www/build/app.esm.js'

To Reproduce
Steps to reproduce the behavior:

1. Stencil.js framework, using Typescript 5.5.2
2. Upgrade marked to 13.0.1
3. Run npm run build

Expected behavior
It should build without any problem

This is the code:

import { Component, Element, Prop, h } from '@stencil/core';
import { marked } from 'marked';
import DOMPurify from 'dompurify';

@Component({
  tag: 'marked-down',
})
export class MarkedDown {
  @Prop() content: string;
  @Element() element: HTMLElement;

  render() {
    const html = marked.parse(this.content) as string;
    this.element.innerHTML = DOMPurify.sanitize(html);
    return <div></div>;
  }
}

Looks like you are trying to compile to a version of JavaScript that does not have class properties.

You will have to transpile marked with something like babel. Or compile your code to a more modern version of ecmascript.
