I can reproduce the hanging build locally with vc build (in the project root — I had to temporarily delete the other vercel project linked to the repo, though apparently it's possible to change the linked project with vc link). Haven't managed to diagnose yet

Alright, the problem was turbo — there's something about this branch it doesn't like. I don't intend to spend any time figuring out why it hangs on this branch but not on master, so I've just updated the build command on Vercel:

-cd ../../ && npx turbo run build --force --filter=kit --filter=kit.svelte.dev && cd sites/kit.svelte.dev
+cd ../../packages/kit && pnpm build && cd ../../sites/kit.svelte.dev && pnpm build

Leaving a comment for others that are upgrading older projects (mine was a couple of months old). I followed the prescribed steps: 1) Install vite as a dev dependency, 2) Update my scripts, and 3) Create vite.config.js. My svelte.config.js file contained config information for vite (config.kit.vite). That entry kept the dev server from starting. Running the 'dev' script will give you an error: "config.kit.vite has been removed - use vite.config.js instead". I removed that entry and the dev server started up fine. Hope that helps somebody!

const config = {
	// Consult https://github.com/sveltejs/svelte-preprocess
	// for more information about preprocessors
	preprocess: preprocess(),

	kit: {
		adapter: adapter(),
		vite: {/*This config info needs to be removed for the dev server to start */}
	}
};

Thank you @jeffkelleran !!!
I copy/paste vite property content into vite.config.js and it works fine !
