React App: Why I get an error when I try to run npm start script?

I installed all required packages and trying to run npm start script which gives me the error below:

TypeError [ERR_INVALID_ARG_TYPE]: The "path" argument must be of type string. Received undefined

Here's copy of my package.json:

{
  "name": "front-end",
  "version": "0.1.0",
  "private": true,
  "dependencies": {
    "@testing-library/jest-dom": "^4.2.4",
    "@testing-library/react": "^9.3.2",
    "@testing-library/user-event": "^7.1.2",
    "node-sass": "^4.13.1",
    "react": "^16.12.0",
    "react-dom": "^16.12.0",
    "react-scripts": "3.3.1"
  },
  "scripts": {
    "start": "react-scripts start",
    "build": "react-scripts build",
    "test": "react-scripts test",
    "eject": "react-scripts eject"
  },
  "eslintConfig": {
    "extends": "react-app"
  },
  "browserslist": {
    "production": [
      ">0.2%",
      "not dead",
      "not op_mini all"
    ],
    "development": [
      "last 1 chrome version",
      "last 1 firefox version",
      "last 1 safari version"
    ]
  }
}

I tried to delete and reinstall the whole project, reinstall node and packages with no luck. Any help is very appreciated!
