I’m having the same problem with Astro. In dev mode everything works fine but when I build the project, it fails. Setting build.cssCodeSplit to false did not help. I’m using unocss 0.45.1

astro.config.mjs

import { defineConfig } from 'astro/config';
import { presetUno } from "unocss";
import unocss from "unocss/vite";
import icons from "@unocss/preset-icons";
import svelte from "@astrojs/svelte";
import { extractorSvelte } from "@unocss/core";


export default defineConfig({
    integrations: [svelte()],
    vite: {
        plugins: [
            unocss({
                presets: [
                    presetUno(),
                    icons()
                ],
                extractors: [extractorSvelte],
            }),
        ],
        ssr: {
            noExternal: ["modern-normalize"]
        }
    }
});

import Header from "../layouts/header.astro";

Setting build.cssCodeSplit to false did not help.

we said set it to true

This actually fixed the issue for me.
