I tested your code snippet and the button does work
maybe something else causing the error ? can you provide a small repo of the error

here is my repository
https://github.com/JackBerck/cool-portfolio.git

maybe u can check it and solve it, thanks sir

Can you try deleting <RootLayout> component from page.js

oh my God... thank you very much, but can I ask. Why does this happen? and in terms of appearance it remains the same even if you dont use a layout

Layouts are auto applied, you don't have to use it as component for it to work

Ouh ok, thank you very much sir
