Sentry Integration causing router to be stuck in `pending` state after v1.98.3

[MTG2000]

Which project does this relate to?

Router

Describe the bug

After updating Tanstack Router to 1.98.3 my app stopped working.
It doesn't render any pages or components and doesn't throw any errors. Just blank page & blank console.

Disabling the sentry tanstack router integration make it work again.

I was using v1.91.3 before & it was working with the Sentry integration without problems.

If I open the router dev tools, I will see all the routes stuck in pending state.

Example available on StackBlitz.

Expected behavior

Sentry integration with Tanstack Router should work as it was in the previous versions.

I just ran into the same issue and struggled to find the root cause since Sentry isn't enabled in the development environment, making it harder to debug.

For now, I just disabled Sentry tracing integration, and everything works.
