React 17 CRA v4.0.1 with new JSX transform not working

[dominikabieder]

I've upgraded react-scripts to 4.0.1 and react to version 17.0.0 (on webstorm), run codemod npx react-codemod update-react-imports --force, but it kept showing 'React' must be in scope when using JSX react/react-in-jsx-scope error. I removed node_modules and package-lock, installed everything again, but the error didn't disappear.

@dominikabieder if it's a VS Code editor issue, this may help: #10144 (comment)

Closing as this is an editor issue, and can be resolved by the suggestion by @rafgraph until VS Code updates their integrated version of TS.
