Accessing `matches` causes TS error on route component declared as an arrow function which uses typegen `Route` type

[pawelblaszczyk5]

I'm using React Router as a...

framework

Reproduction

https://github.com/pawelblaszczyk5/matches-circular-repro

1. Go to app/routes/home.tsx
2. Observe TS error

On the other hand, if I declare component as a function declaration it doesn't cause type error

Same if I don't access the matches prop

Expected Behavior

I can access every component prop without TypeScript error regardless of the way I declare route component

Actual Behavior

Accessing matches from generated type on route component declared as arrow function causes TS error
