Expo App crashes in Production mode

My app crashes when I start to run it in production mode. In dev mode all works correctly. Only logs I have on the screen. What can I do?

I found solution. It’s all because of wrong auto import.

I have imported useState from “react/cjs/react.development”, not from ‘react’.

Instead

import { useState } from "react/cjs/react.development";

I need write

import React, { useState } from "react";
