What does the error mean when working with react redux?

Question

React

Hello! I wanted to try redux after theoretical training and it doesn’t even work out.

I create a store

import { createStore } from "redux"
import { myReducer } from "./myReducer";
import { compose } from "redux";

const store = createStore(myReducer, compose(window.__REDUX_DEVTOOLS_EXTENSION__ && window.__REDUX_DEVTOOLS_EXTENSION__()));

export default store;

I create a reducer

const defaultState = {
    rabby: 1
} 
export const ACTION_ONE = "ACTION_ONE"
export const ACTION_TWO = "ACTION_TWO"

export const myReducer = function (state = defaultState, action) {
    switch (action.type) {
        case ACTION_ONE: return {...state, rabby: state.rabby + action.payload};
        case ACTION_TWO: return {...state, rabby: state.rabby - action.payload};
        default: return state;
    }
};

I wrap in Provider

import React from "react";
import ReactDOM from "react-dom";
import store from './store/store';
import App from "./App";
import { Provider } from "react-redux";

ReactDOM.render(
  <React.StrictMode>
    <Provider store={store}>
      <App />
    </Provider>
  </React.StrictMode>,
  document.getElementById("root")

I get an error
