application cannot be run on localhost or with github page

Can I ask for help? Initially, the application that I built using React JS could run on localhost. However, when I try to deploy using GitHub pages, the application cannot be run even though the React code has been deployed to GitHub.
This is the json package that I set to deploy with GitHub pages
{
"name": "movie-app",
"version": "0.1.0",
"homepage": "http://xcage88.github.io/movie-app",

]
},
"devDependencies": {

}
this is code index and app.js
App.js :
import { Route, Routes } from 'react-router-dom';
import SignUp from './component/SignUp';
import ForgotForm from './component/ForgotForm';
import LoginForm from './component/LoginForm';
import MainPage from './component/MainPage';
function App() {
return (
<div>
<div>
<Routes>
<Route path='/' exact element={<LoginForm/>}/>
<Route path='/forgot' element={<ForgotForm/>}/>
<Route path='/sign-up' element={<SignUp/>}/>
<Route path='/main/*' element={<MainPage/>}/>
</Routes>
</div>
</div>
);
}
export default App;
index.js:
import React from 'react';
import ReactDOM from 'react-dom/client';
import './style/style.css'
import 'bootstrap/dist/css/bootstrap.css'
import 'bootstrap/dist/js/bootstrap.bundle'
import reportWebVitals from './reportWebVitals';
import {BrowserRouter} from 'react-router-dom'
const root = ReactDOM.createRoot(document.getElementById('root'));
root.render(
<React.StrictMode>
<BrowserRouter>
<App />
</BrowserRouter>
</React.StrictMode>
);
when I try to run it, the result is like this:
run in GitHub pages
run in localhost
if you want to try it, click or copy/paste the link below
react app

I can't exactly tell you why you are getting the error from the first screenshot. It seems like it is some Google-Thingy.
I found this related question and it seems like you have to set a flag to ignore or disable this "feature". As I looked further into the topic, in your case it's more about enabling the feature instead of disabling.
Error with Permissions-Policy header: Unrecognized feature: 'interest-cohort'
Maybe you find more when you search for "floc google".
For your localhost problem, it seems like the path is just / instead of /movie-app.

React chunk file ERR_ABORTED on reloading the page

I have a react component in this path: host/qr-ui/v1/report-detail/:year/:quarter
which is not my home page. when I reload it I get this error:
GET ../qr-ui/v1/report-detail/:year/static/js/2.e2743d9e.chunk.js net::ERR_ABORTED 404
well my static file is not here. but why it cannot find the location to static file.
I'm using react-scripts. and this is my package.json
{
"name": "qr-ui-v1",
"version": "0.1.0",
"private": true,
"homepage": ".",
"dependencies": {

"not dead",
"not op_mini all"
],
"development": [
"last 1 chrome version",
"last 1 firefox version",
"last 1 safari version"
]
}
}
and this is my app.js
import React from 'react';
import './App.css';
import './css/Button.css';
import './css/Jumbo.css';
import './css/Form.css';
import ReportManagerComponent from './components/ReportManagerComponent.js'
import ReportDetailComponent from './components/ReportDetailComponent.js'
import Nav from './components/Nav.js'
import {
BrowserRouter as Router,
Switch,
Route,
} from 'react-router-dom';
function App() {
return (
<React.Fragment>
<Router basename='/qr-ui/v1'>
<Nav/>
<Switch>
<Route exact path='/' component={ReportManagerComponent} />} />
<Route exact path='/report-detail/:year/:quarter' component={ReportDetailComponent} />}/>
</Switch>
</Router>
</React.Fragment>
);
}
export default App;
In first component I redirect to the second one but cannot load the second one directly.

Weird problem in react: (C:\): Error: EBUSY: resource busy or locked, lstat 'C:\hiberfil.sys'

I'm currently working on a MERNG app, and i was doing the setup in the fronted, and, when i ran npm run start, this error suddenly appeared
Error from chokidar (C:\): Error: EBUSY: resource busy or locked, lstat 'C:\hiberfil.sys'
Compiling...
i've searched for this problem, and i found that, you should delete node_modules, then run npm intall, i tried, didn't work
This is my package.json

}
}
This is my index, i put there my apolloProvider and my redux setup
import React from "react";
import ReactDOM from "react-dom";
import ApolloProvider from "./ApolloProvider";
import { Provider } from "react-redux";
import { createStore } from "redux";
import { reducer } from "./reducer";
const store = createStore(reducer);
ReactDOM.render(
<Provider store={store}>{ApolloProvider}</Provider>,
document.getElementById("root")
);
This is my apollo provider
import React from "react";
import {
ApolloClient,
InMemoryCache,
ApolloProvider,
createHttpLink
} from "#apollo/client";
import App from "./App";
const httpLink = new createHttpLink({
uri: "http://localhost:5000"
});
const client = new ApolloClient({
link: httpLink,
cache: new InMemoryCache()
});
export default (
<ApolloProvider client={client}>
<App />
</ApolloProvider>
);
What is going on with my react app? i'm mad at this because it came out of nowhere, any clue how to fix this? And thank your four time comunnity !

React.JS: Error: Invalid hook call. Hooks can only be called inside of the body of a function component

I have been working on a front-end (following a tutorial) for React.js and have ran into an error:
× Error: Invalid hook call. Hooks can only be called inside of the body of a function component. This could happen for one of the following reasons:
You might have mismatching versions of React and the renderer (such as React DOM)
You might be breaking the Rules of Hooks
You might have more than one copy of React in the same app
I have looked into each one of these issues and cannot seem to find the problem.. If anyone has a pointer that would be very helpful..
The 'App' Code:
import React from "react";
import { Container, AppBar, Typography, Grow, Grid } from "#material-ui/core";
import memories from "./images/memories.png";
const App = () => {
return (
<Container maxwidth="lg">
<AppBar position="static" color="inherit">
<Typography variant="h2" align="center">
Memories
</Typography>
<img src={memories} alt="memories" height="60" />
</AppBar>
</Container>
);
};
export default App;

],
"development": [

]
}
}
The 'index.js' Code:
import React from "react";
import ReactDOM from "react-dom";
import App from "./App";
ReactDOM.render(<App />, document.getElementById("root"));
EDIT: as requested, i've added a few more files which maybe causing the issue.

shallowWrapper is empty, testing snapshot Jest/Enzyme?

I don't know why i get empty shallowWrapper object when i run snapshot test, i am using Jest and Enzyme:
What i get in App.test.js.snap file:
// Jest Snapshot v1, "goo.gl/fbAQLP"
exports[`renders App component 1`] = `ShallowWrapper {}`;
my package.json file:

},

"jest": "^26.4.2"
}
}
App.test.js file
import { shallow } from 'enzyme';
import React from 'react';
import App from './App';
it('renders App component', () => {
expect(shallow(<App />)).toMatchSnapshot();
})
setupTests.js file:
import { configure } from 'enzyme';
import Adapter from 'enzyme-adapter-react-16';
configure({
adapter: new Adapter()
});
Why i get that empty shallowWrapper object, I suspected the version of jest after some search, but even downgrading didn't solve it.

I ran into similar problem and playing around with jest help me got through it. I suggest you can clear the jest cache and then update the snapshots using jest --clearCache && jest -u and then run your test.
Also for your snapshot, I'd recommend you to use enzyme-to-json serialiser (https://www.npmjs.com/package/enzyme-to-json) and modify your test to:
import { shallow } from 'enzyme';
import React from 'react';
import App from './App';
import { shallowToJson } from 'enzyme-to-json';
it('renders App component', () => {
const app = shallow(<App />);
expect(shallowToJson(app)).toMatchSnapshot();
})

The shallow( ) did returned the output. Shallow works as a wrapper instance with the rendered output. You could use shallow( ) method with debug( ) to see what prints out. If you want to see the rendered output，you could use shallow().html( ) inside the expect( ) method to test again.
