core: Error in built docs: ``Referapp.c20e2fa1.js:1 Uncaught ReferenceError: Cannot access 'j' before initialization``

Description

Hello,

followed the documentation and started a new vuepress project using 2.0.0-beta.52 Works fine and great in local dev but built docs throw errors and seems like all js fails because of it (e.g. search, selection of theme light<>dark)

STRP:

go to src
run npm install
run npm run docs:build
Upload .vuepress dist folder to some FTP or deploy to github pages
observe error in console

config:

import { defineUserConfig, defaultTheme } from 'vuepress'

export default defineUserConfig({
    base: "/wiki-test/",
    lang: 'en-US',
    title: 'Title',
    description: '....',
})
