routeTree is failing to generate, saying that a semicolon is missing

[DestroyCom]

Hello,
I have a problem that I can't solve, I installed tanstack router on my react vite project but when I do “npm run dev”, I get an error that says SyntaxError: ';' expected. (43:19)

There is my repository: https://github.com/GoofyComponent/RandomGraill/tree/intergrate-router

I tried everything, event to downgrade packages but i cant find whats happening.

I really hope you can help me 🙏

SyntaxError: ';' expected. (43:19)
