Nextjs 15 introduced some breaking changes, where the pageprops are now Promises. This might help you out: #71997.

In my case, this issue remains after downgrading from 15.x.x to 14.2.3. After removing node_modules and package-lock.json and re-installing my package.json file, I receive the same errors while building the app

Apparently, Next15 creates a build folder outside the .next folder. This build folder is then referenced after the downgrade. Removing the build folder solved the problem

@eltongonc thank you for help, but i found the problem that i use React.FC in each page.tsx without props, i think its the problem for me, so i removed them and it works. i never though that can be the problem
