I tried various approach described above but none of them worked since I have ejected my css. Finally applying following steps helped:
react-scripts
from "react-scripts": "3.x.x"
to "react-scripts": "^3.4.0"
react-dev-utils
form "react-dev-utils": "^10.x.x"
to "react-dev-utils": "10.0.0"
node-modules
folder and package-lock.json
/yarn.lock
npm install
/yarn install
