You should not compile postcss-load-config with Vite. It is Node.js module.

Nothing in my project for postcss.

Package.json

{
    "private": true,
    "scripts": {
        "dev": "vite",
        "build": "vite build"
    },
    "devDependencies": {
        "@vitejs/plugin-vue": "^3.1.2",
        "axios": "^0.27",
        "laravel-vite-plugin": "^0.6.1",
        "lodash": "^4.17.21",
        "vite": "^3.1.8",
        "vue-loader": "^17.0.0"
    },
    "dependencies": {
        "browser-sync": "^2.27.10",
        "dotenv": "^16.0.3",
        "secure-ls": "^1.2.6",
        "vue": "^3.2.36",
        "vue-persistedstate": "^1.2.5",
        "vue-router": "^4.1.6",
        "vuex": "^4.0.2",
        "vuex-persistedstate": "^4.1.0"
    }
}

vite.config.js:

import { defineConfig } from 'vite';
import laravel from 'laravel-vite-plugin';
import vue from '@vitejs/plugin-vue';

export default defineConfig({
    plugins: [
        laravel(['resources/js/app.js']),
        vue({
            template: {
                transformAssetUrls: {
                    base: null,
                    includeAbsolute: false,
                },
            },
        }),
    ],
});

app.vue:

<template>
      <div>
        <router-view></router-view>
      </div>
</template>

app.js:

import vue from '@vitejs/plugin-vue'
import App from './App.vue'
import router from './routes'
import store from './store'
import '../css/app.css';
import './bootstrap';

new vue({
      router,
      store,
      render: function (h) {
        return h(App)
      }
    }).$mount('#app')

Check all imports in your project. Somewhere you import some tool, which has PostCSS dependency inside. It adds this dependency to client-side JS bundle and Vite compiles process.env.NODE_ENV in postcss-load-config sources.

The only thing including postcss is Vite. So it must be a problem with their package.
