Reproduction

I have installed the latest version of nuxt and the @pinia/nuxt module. With @pinia/nuxt the page can no longer be loaded.

Steps to reproduce the bug

Dear team,
I have installed the latest version of nuxt and the @pinia/nuxt module. If I remove pinia in the nuxt.config.ts under modules the page works. but if I add it the page cannot be loaded see error below.
I tried a lot with ChatGPT to solve the problem but without success.
Thank you very much
