create-react-app: 'Npm start' fails on react-scripts-start

I have 4 projects bootstrapped using create-react-app. One of the projects is working completely fine. However, with the other three, upon using “npm start”, the app is crashing. The complete error message and debug output have been shared:

Error message:

Methods tried to fix the issue:

• I removed the package.json file and node_modules directory, and ran npm install.

• I reinstalled node and npm.

• I reinstalled create-react-app and react-scripts-start
