Incompatible TypeScript version in package.json

See original GitHub issue

The minimum TS version listed in package.json when creating a new CRA project is 4.0.3, which not compatible with the new JSX transform and the included tsconfig.json setting "jsx": "react-jsx"

This is ultimately the root cause behind #10144 because when package.json lists a compatible TS version, VS Code knows not to use an incompatible version.

Solution: change the TS version in newly created CRA projects to "typescript": "^4.1.2"

@rafgraph This is solved to me. I started a project and found the same problem as you. I just upgraded the typescript as mentioned and it worked 100% for me, clearing all compilation errors and the new jsx-transform is also working.

Thanks!!!
