I had the same. node v22.9.0 | yarn | "nuxt": "^3.15.0"

yarn add vite typescript helped in my case

"typescript": "^5.7.2" | "vite": "^6.0.7"

@Tristwch not sure you need Vite as explicit dependency, as nuxt 3.15.x adds Vite 6.
But adding typescript as dev dependency fixed it. Thanks for the hint. (:
