Svelte-check --watch doesn't watch any longer in version 4.3.2 (works in 4.3.1 and earlier)

[Al38andr0]

Describe the bug

As for the title, I unfortunately don't have any more details available; it just doesn't re-run after any file has changed.

Since I'm here, does anyone know why it runs twice (most often, but not always) when it starts?

Thank you.

Reproduction

Execute the command: npx svelte-check --watch or npm run svelte-check --watch (passing the proper configuration and variables, if needed).

Modify any TS or Svelte file.

The console doesn't refresh the results.

Expected behaviour

For versions 4.3.1 and earlier, I expect to see the Svelte-check result updated every time any of my files change.

The main issue is a duplicate of #2855. As for why it runs twice when initialised, it's usually because vite-plugin-svelte's vite-preprocess triggers SvelteKit to regenerate the ./svelte-kit/tsconfig.json. I'll see what we can do to prevent it. (I tried it before, but haven't figured out an efficient way to do it. )
