"npm run start" not creating a local server for my react app

I'm new to React JS I created my react app using "npx create-react-app" When the app is created successfully I tried to run the app with the following command "npm run start", but the ap doesn't create a local server it will just pop with the pic below

And when I select chrome it opens nothing below is the screenshot of the page in chrome

I'm currently using node version 14.16.1 Thanks for helping out
