Reproduction

Bug Realization Methods

• npx create-next-app@latest

• yarn add @unocss/postcss@0.59.0 or yarn add @unocss/postcss@0.59.2

• postcss.config.js

  module.exports = {
    plugins: {
      '@unocss/postcss': {
        content: ['**/*.{html,js,ts,jsx,tsx}'],
      },
    },
  }

Had same error.
The reason is that after building, the default export of CJS was replaced.

But Next.js plugins must be provided as strings.

You can roll back to version 0.58.9 until a solution is found.
