Describe the bug
After upgrading Nuxt to v4 (though I've been using v3 in v4 compatibility mode for a while), deno dies when attempting to load the first page. I created a new repo to test this by itself. I install Nuxt using nuxi, and select Deno. I do include Nuxt UI (and Nuxt Font and Image as well).
