Issue persists.
npm --> 10.9.0
npx --> 10.9.0

[justincrich]

Same issue... any workaround?

[LautaroLobo12]

it seems like create-react-app is unmantained. maybe use vite instead?

If you downgrade to version 18.3.1 you can run normally.

  "dependencies": {
    "cra-template": "1.2.0",
    "react": "18.3.1",
    "react-dom": "18.3.1",
    "react-scripts": "5.0.1",
    "web-vitals": "^4.2.4"
  },

I have encountered the same problem. Is there a successful solution?

@carrey493 you can use Vite or downgrade react to version 18.3.1
