Create React App throws error while starting server

This error shows up whenever I run npm start.

I've tried npm install. I have no errors in the console.

Also I'm not using JSON.parse in any of my files.

Full error:

Starting the development server...

C:\Users\user\Documents\GitHub\repo\client\node_modules\react-scripts\scripts\start.js:19
  throw err;
