During client-side navigation (e.g., transitioning from /table/latest/docs/overview to /table/latest/docs/framework/react/examples/basic), TanStack Router can render the destination route component while the async loader is still pending.

RouteComponent was immediately accessing data.kind without checking if data had resolved, throwing TypeError: can't access property "kind", r is undefined. Adding an early if (!data) return null prevents the crash until the loader resolves.

Fixes TANSTACK-COM-54C

Can we include a regression for the navigation that triggers this? I'd like to understand why the loader data is missing before we turn that state into an empty page.

AI review notes:
The change at 4d6d7bcf adds only an early null return in the example route component. It prevents the immediate data.kind access, but adds no regression coverage showing that the example eventually renders.
Please include the event trace or a minimal reproduction behind TANSTACK-COM-54C, and cover navigation from the Table overview to the basic React example, including the pending and resolved states. This is requested coverage, not a claim that the reported navigation failure has been reproduced independently.
