Circular import causes strange cryptic error

Which project does this relate to?

Router

Describe the bug

This repo https://github.com/arackaf/tanstack-start-blog-dataloading/tree/special/start-bug-2 -- note the branch! special/start-bug-2
npm i

npm run dev
SECOND TERMINAL - npm run server

Go to the epics page. Edit an epic, and hit save.

Server function will error out. Reason is because of the queryClient import that's used in the client middleware. There's some incorrect bundling happening. Basically, if I move the queryClient export to its own file, it works just fine. So there seems to be some bundling shenanigans

Looks like this was a circular dep issue that manifested itself in a weird way. We should consider adding https://www.npmjs.com/package/vite-plugin-circular-dependency to our dev deps when convenient.
