Describe the bug

The compiler is missing, buildStart mutating the compiler but options is a shallowRef. The SB reproduction will fail with any package manager.

On local it works, only failing on StackBlitz, breaking any Nuxt + I18n reproduction...

You can check this repository using pnpm (instead npm) patching the Vue plugin to initialize the compiler properly in the configResolved hook:

Link to SB in the readme file: https://github.com/userquin/nuxt3-starter-patched-vue-plugin

I'm going to send a PR to fix this.

Reproduction

https://github.com/userquin/nuxt3-starter-patched-vue-plugin

Steps to reproduce
