Reproduction

can't share code due to corporate law
if very necessary I will try to create an electron-fiddle

Describe the bug

In my electron app I am using Nuxt and have been migrating from v2 to v3 over the last few days.

Now when calling my builder function in main.js I get the error

TypeError: Cannot read properties of undefined (reading 'map')
 at initNuxt (nuxt/dist/index.mjs:3928:46)

for this

async function readyNuxt() {
  const { createNuxt } = await import('nuxt')
  nuxt = createNuxt(configDev)
  nuxt.hook('build:done', () => {
    const application = express()
    application.use(nuxt.render)
  })
  nuxt.ready()
}

and

TypeError: Cannot read properties of undefined (reading 'flatMap')
at resolveApp (nuxt/dist/index.mjs:4781:28)

for this

async function readyNuxt() {
  const { createNuxt, build } = await import('nuxt')
  nuxt = createNuxt(configDev)
  nuxt.hook('build:done', () => {
    const application = express()
    application.use(nuxt.render)
  })
  build(nuxt)
}

In Nuxt 2 this worked perfectly:

async function readyNuxt() {
  const { Nuxt, Builder } = await import('nuxt')
  nuxt = new Nuxt(configDev)
  const builder = new Builder(nuxt)
  builder.build()
  nuxt.hook('build:done', () => {
    const application = express()
    application.use(nuxt.render)
  })
}

I know that there are libraries like nuxt-electron that take over a lot of the work here but would prefer keeping my own implementation for now.
