🐛 The bug

file://------/node_modules/.pnpm/@next-devtools+core@0.3.0-b_950081b16bd148b95e0a39fde9b645c2/node_modules/@next-devtools/core/dist/es/plugin.mjs:23
import { loadEnvConfig } from '@next/env';
         ^^^^^^^^^^^^^
SyntaxError: Named export 'loadEnvConfig' not found. The requested module '@next/env' is a CommonJS module, which may not support all module.exports as named exports.
CommonJS modules can always be imported via the default export, for example using:

import pkg from '@next/env';
const { loadEnvConfig } = pkg;
