Hello! I am creating a React App. I already used this commands:
npx create-react-app my-app
cd my-app
npm start

But, when I go to my browser (Chrome) I see this.:

And in the console I don’t see any errors.
Can you help me? please

Apparently, it can be caused by the Grammarly browser extension. Try it in an incognito window with no extensions.


I would highly suggest using Vite as does the React docs (unless you need a meta-framework).

it seams to be caused due to any extension.
