Additional context

Recently React team removed experimantal_ prefix from some hooks facebook/react#27459.
I see that Next.js uses under hood experimental version of the React library where useOptimistic does not require prefix but at build is used stable version of React what causes error and fails build (?)

This is not something Next.js could fix at the moment, as our version of React does not match with those types yet. You can pin the types to "@types/react": "18.2.26" for now.

The change to remove the experimental_ prefix (see diff below) is now working in the latest Next.js canary version (currently next@13.5.7-canary.23)

-import { experimental_useFormStatus as useFormStatus } from 'react-dom';
+import { useFormStatus } from 'react-dom';
