Describe the Bug

When I tried playing with the experimental I was not able to build my application when bother turboMode and babelMultiThread were enabled

I have a basic custom App (only changing the render method)

Error occurred prerendering page "/***". Read more: https://nextjs.org/docs/messages/prerender-error

Expected Behavior

next build should successfully build the application

To Reproduce

• create a NextJS application that have static prerendered pages
• set both turboMode and babelMultiThread to true
• run next build
• see the error

This is correct, you shouldn't use babelMultiThread as it's an experiment.
