Depending on the way you initialized your project, you may have a main.jsx (when using create-vite) or index.js (when using create-react-app). If it's not there already, you should move your ReactDOM.createRoot(...) call to one of these files, to avoid calling it multiple times (and fix your error). – Szigeti Péter Commented Apr 11, 2023 at 11:09
sorry bro i didn't understand also there is not a single file in project with extension jsx and also there is no main.jsx, So i don't know where i should move this function, please be more simpler – Akki Jangir Commented Apr 11, 2023 at 11:21
Sure, I'll try. How did you begin the project? Did you use create-react-app? – Szigeti Péter Commented Apr 11, 2023 at 12:55
yes i use create-react-app – Akki Jangir Commented Apr 12, 2023 at 5:04

Sorted by: Reset to default 0 I think you misunderstood the way that reacts works.
your app ponent is called by the main or index ponent that has the render function in it.
I think you should move the router ponent in the app function and let the main.js file render
by the way, I don't know if this syntax for the router is correct or not and another tip:
Don't Use create-react-app. It's dead! you can see docs in react.dev

if still not resolved try

import { PayPalScriptProvider, PayPalButtons } from "@paypal/react-paypal-js";

and add

<PayPalScriptProvider>
   <PayPalButtons {...Your code here}/>
</PayPalScriptProvider>

when using React JS
