Reactjs – React application working perfectly fine. But stopped working after restarting laptop

I built a website using React, Node.js, MongoDB, Tailwind. Everything was running fine. I restarted my laptop and when I un npm start, it just says "Server running on HTTP://localhost:5002" and "connected to MongoDB", but the application never starts on localhost:3000.

I have been trying for hours to figure out whats going on but I just can’t. I don’t have any errors either because the code works fine like I said. Any help please!

    To resolve your issue, you can try the following steps:

    • Run the React development server: Navigate to the React project folder and run npm start to confirm the frontend is starting.

    • Check for port conflicts: Ensure the frontend is running on http://localhost:3000 and the backend on http://localhost:5002. If port 3000 is in use, stop it using npx kill-port 3000 and restart.

    • Verify proxy in React: In the React package.json, confirm "proxy": "http://localhost:5002" is set to route API requests correctly.

    • Reinstall dependencies: Delete node_modules in both frontend and backend folders, run npm install, and start the servers again.

    If the issue persists, check the browser’s developer console and network tab for errors.
