Nextjs Bug after downgrading node and then reinstalling back to the original version of node

Question

I had to remove the current version of the node and downgrade to a later version to finish up with another project. Afterwards I reinstalled back to version 20 of node, but my nextjs project hasn;t been working ever since!!!

PS C:\Github\portfolio.2.0> npm start

> [email protected] start
> next start

   ▲ Next.js 14.0.1
   - Local:        http://localhost:3000

[Error: ENOENT: no such file or directory, open 'C:\Github\portfolio.2.0\.next\BUILD_ID'] {
  errno: -4058,
  code: 'ENOENT',
  syscall: 'open',
  path: 'C:\\Github\\portfolio.2.0\\.next\\BUILD_ID'
}

any one know how to fix this?

I should have been able to run the application. Now its says the buildid file is missing?

Looks like there is no build folder. Run 'npm run build' script to build your project and then run 'npm run start'.
