This change creates nested HTML structure, which is invalid. Both the root layout (app/layout.tsx) and the child layout (app/[lang]/layout.tsx) now have html and body tags. In Next.js App Router, only the root layout should contain these tags. The [lang]/layout.tsx should be updated to remove its html and body tags and only wrap children with the RootProvider component. This will result in nested HTML like: html > body > html > body, which browsers will not render correctly.

Suggested change
return (
<html lang="en" suppressHydrationWarning>
<body>{children}</body>
</html>
);
}
return children;
}
