Nuxt v5 with TUI error and terminal hangs

I'm testing Nuxt v5 on a huge repo using Nuxt 4.6.3, after some minimal changes at nitro configuration, the app is running, but the TUI hangs after a few navigations:

node error at TUI

Running nuxi manually with --trace-warnings, this is the error:

node --trace-warnings ./node_modules/@nuxt/cli/bin/nuxi.mjs dev --envName web

Disabling TUI the node error just disappears:

running nuxt dev server without TUI

cannot get proper event types, this seems to fix the issue, srvx seems to be fine:

// server/plugins/listeners.ts
export default defineNitroPlugin((nitroApp) => {
  nitroApp.hooks.hook('request', (event) => {
    if (event.req.getMaxListeners() === 10) {
      event.req.setMaxListeners(20)
    }
  })
  nitroApp.hooks.hook('response', (event) => {
    if (event.getMaxListeners() === 10) {
      event.setMaxListeners(20)
    }
  })
})

arggg, still failing, changing the defaultMaxListeners doesn't fix the error:

import events from 'node:events';

events.defaultMaxListeners = 20;

export default defineNitroPlugin(() => {})
