Answer 1

You are running npm start in incorrect folder.Also why there is package-lock.json outside.

move to D:\React\operations_app_tut\operations_app_tut directory then run npm start

Answer 2

Thanks @NitinDev And @Adithya.

Adding details if future contributor faces the same issue -

My mistake here was, I had a folder D:/React Within this folder I had all my react projects. I manually created - operations_app_tut folder in D:/React

After this I opened it through Visual Code via path:- D:/React/operations_app_tut and ran command -

npx create-react-app operations_app_tut

This command created another folder within operations_app_tut which made my project path to be - D:/React/operations_app_tut/operations_app_tut

Since I was running npm start on terminal with path - D:/React/operations_app_tut which was not the actual path, it was giving me error.

Lesson -

1. Do not create Project Folder Manually, it will automatically get created via npx create-react-app
