I've updated to Next1 5, and now when i run npm run dev, then open the app in my browser, it logs that it's compiling the route then exits with code 0 without any output.

Using --inspect complains that the port is already in use 3 times (which it isn't before running npm run dev)

Using --trace-exit provides nothing

Increasing memory limit does nothing

It only affects Turbopack - but I can't use webpack because of another bug

It does work when I disable a Tailwind plugin, but it also works when I leave that in and remove a bunch of imports from page.tsx - suggests memory is the problem?

I can't reproduce the issue with a fresh next install

Not using docker

Please send help

can u try disabling the debugger and see if that helps?
before v15 migration, was it working?
seems like its stuck on compiling your dynamic route
do you do some unusual things in layout.tsx or page.tsx?

It was working before v15 yep, nothing unusual in layout.tsx or page.tsx

I've narrowed it down now to the Preline Tailwind plugin.

I have a utility module which resolves the Tailwind config so that the screen breakpoints can be reused

import resolveConfig from 'tailwindcss/resolveConfig';
import baseTailwindConfig from '@/../tailwind.config';

export const tailwindScreens = resolveConfig(baseTailwindConfig).theme.screens as Record<
  'sm' | 'md' | 'lg' | 'xl' | '2xl' | '3xl' | '4xl',
  string
>;


If I comment out Preline from plugins in the TW config, it works.

It seems that whenever baseTailwindConfig is read, it breaks. So if I comment out the resolveConfig line, it no longer breaks. If I add console.log(typeof baseTailwindConfig), it breaks.
