create-vite: vanilla-ts template appears to be broken

Describe the bug

npm create-vite@latest with the vanilla-ts template produces a broken build. I have got the same results with Node versions 20 and 22 and with npm and pnpm package managers. I assume that there is a bug with reading or parsing JSON files. Please see the full reproduction in the attached repo.

Reproduction

https://github.com/amelekhin/vite-vanilla-ts

Steps to reproduce

Initialize a new project with npm create-vite@latest. Choose any name, vanilla template, and TypeScript as a language. Follow the instructions of the setup utility.
Run npm run dev.
