Reactjs – Fail to run/build project – next js

I’hv been doing tutorial from JSMastery about figma and locofy.

The problem is when i try run the project in vscode.

when I try npm start this problem appear:

Error: Could not find a production build in the '.next' directory. Try building your app with 'next build' before starting the production server. https://nextjs.org/docs/messages/production-start-no-build-id

    at async Server.<anonymous> (D:Projectrealestaterealestate_locofynode_modulesnextdistserverlibstart-server.js:249:36)

I also have search the solution about this problem and most of the answer is by using npm run build/npx next build.

I tried and this happened
