Can someone help me understand why I'm having this error? I just recently transferred to React 16.8.4 from React 15 and changed one class component into a functional component with hooks, unfortunately it complains that useState is not a function and I don't think I did anything wrong with how I used it...
React is complaining about this line
const [isChanged, setIsChanged] = useState(false);
It's not a problem with the certain component, I can't use useState or any hooks for that matter ANYWHERE, app doesn't break, but component doesn't load and I get and error in the console.
here is the screenshot of the error
here are my dependencies.
