No export named `useSyncExternalStoreWithSelector` with Tanstack Start

[GenericNerd]

Describe the bug

Whenever the useForm hook is used within a Tanstack Start project, the following error appears:

The requested module '/node_modules/.pnpm/use-sync-external-store@1.6.0_react@19.2.0/node_modules/use-sync-external-store/shim/with-selector.js?v=b2949b83' does not provide an export named 'useSyncExternalStoreWithSelector'

Steps to reproduce

1. Create a new Tanstack Start project via pnpm create @tanstack/start@latest
2. Install @tanstack/react-form-start
3. Import and attempt to use a form variable through the useForm hook.

Expected behavior

I expect the useForm hook to not through an export not found error.
