Cannot find svelte inspector when running dev server

[f-llewellyn]

Describe the bug

Recently had to reinstall Windows and am trying to pick my svelte-kit project back up again. I get the following issue when trying to run the dev server:

error when starting dev server:

SyntaxError: Named export 'svelteInspector' not found. The requested module '@sveltejs/vite-plugin-svelte-inspector' 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 '@sveltejs/vite-plugin-svelte-inspector';
const { svelteInspector } = pkg;

This appears to be an issue with pnpm, as when following the repro steps with npm the issue does not occur.
