Issue Description

The error occurs when the number of page files in the project reaches a certain threshold. The TypeScript compiler throws an error stating that keyof RouteNamedMap is incompatible with the expected parameter type of router.push().

Notably, the error disappears immediately after removing just one page file (regardless of which page is removed). When the number of pages is below that threshold, the type checking works as expected without any errors.
