This worked for me.

Update the development array in package.json

“development”: [
“ie 11”,
“last 1 chrome version”,
“last 1 firefox version”,
“last 1 safari version”
]
}
Add the below code in index.js in the src folder

// These must be the first lines in src/index.js
import ‘react-app-polyfill/ie11’;
import ‘react-app-polyfill/stable’;
Then delete the node_modules folder and run

npm install
