Only when you change the version of shadcn-nuxt to version 0.10.4 can you get your project to run.

    // package.json
    "shadcn-nuxt": "^0.10.4",

The issue is that shadcn-nuxt does not depend on the module - you need to install it yourself:

https://github.com/unovue/shadcn-vue/blob/dev/packages/module/package.json#L48

The error message in Nuxt will make this clearer in the next version (v3.15) via nuxt/nuxt#30116.
