react-scripts 4.0.0 not working

[Priyanshu-Desai]

In my react app I use react-scripts 4.0.0. When I run my react app with npm start, react-scripts fails to start my react app. When I downgrade react-scripts to 3.0.0 and run npm start, the app successfully runs. Please fix this problem in react-scripts 4.0.0.
