I fixed my problem :

run 

npm install react@latest
and 
npm install react-dom@latest
its worked for me

In package.json now reads

"react": "^16.8.6", "react-dom": "^16.8.6"

It is actually a version miss match so updating the your react-dom, react & redux packages would solve the issue

npm update react react-dom
