LayoutData not correctly inferred

[simonh1000]

Describe the bug

+layout.ts

export const load = (async ({ url }) => {
    try {
        let user: null | { user: string, player: string } = await Promise.resolve(null);
        return user;
    } catch (err) {
        throw redirect(301, "/login");
    }
}) satisfies LayoutLoad

in +layout.svelte

<script lang="ts">
	import type { LayoutData } from './$types';

	// Data from +page.ts
	export let data: LayoutData;
    let user;
    if (data) {
        user = data.user;
    }
</script>

LayoutData is inferred as {} which then leaves lots of other errors in the my code

Reproduction

See description

Expected behaviour

LayoutData should be null | { user: string, player: string }

I ran into a similar issue on arch linux using emacs and lsp-mode, turns out I still had the package nodejs-svelte-language-server-git installed (it must've been removed from the aur sometime after I installed it) and updating to a more recent version (0.15.3) using the nodejs-svelte-language-server package fixed it.
