Vscode - Cannot find module './App.svelte' or its corresponding type declarations.

Describe the bug

When the extension installed after scaffolding a project if I open main.js, vs code complains about the error even though everything is perfectly working and valid.

Reproduction

npm init vite my-app -- --template svelte
cd my-app
npm install
npm run dev

And open VS Code.

Expected behaviour

Should not complain

Experienced the same with a fresh install with Svelte (Typescript) via Yarn 2. Adding this in svelte.config.js fixed the issue temporarily, but doing changes in files outlines errors again:

/** @type {import('@sveltejs/kit').Config} */
const config = {
	// Consult https://github.com/sveltejs/svelte-preprocess
	// for more information about preprocessors
	preprocess: preprocess(),
	"enable-ts-plugin": true, **<-- THIS ONE**
	kit: {
		adapter: adapter()
	}
};

The installation was fresh, so this is still a bug and not fixed.

Ah right. that’s the problem. We indeed didn’t check the config in the “remove the ambient type definitions” logic. Ironically what I said you can try is the actual reproduction of the problem. Sorry I didn’t check it more.
