When the Chrome window is open and I try to run Chrome Debug Instance, I get the error:

The application does not appear, and a blank tab is loaded, at the url "about:blank".

Steps to reproduce:

1. Create a react application:

npx create-react-app my-app
cd my-app

2. Create an Eclipse project in my-app folder.
3. Edit the file my-app/package.json adding the following line to the scripts key:

    "debug": "react-scripts --inspect=127.0.0.1:9222 start"

4. Start the application with the command:

npm run debug

5. Access the Eclipse menu:
   Run -> Debug Configurations -> Running Chrome Debug Instance

And create a new configuration.
6. Fill the URL field with: http://localhost:3000
7. Click in Apply
8. Click in Debug

When all Chrome windows are closed, the issue does not occur. However, it is bad to have to close Chrome every time we go to debug.

Environment

Eclipse 4.25.0
Java 18
Ubuntu 22
node 16.17.0
Chrome 105
wildweb 0.15.1

Riprodurre il malfunzionamento seguendo i passaggi indicati con React, Node.js, Chrome ed Eclipse, quindi tracciare il percorso di avvio attraverso ChromeAttachDebugDelegate.launch e l’inizializzazione del debug DSP mostrata nello stack trace. Confrontare il comportamento con tutte le finestre di Chrome chiuse e con una finestra di Chrome esistente; il lavoro è completato quando viene trovato l’URL localhost configurato e il debug si avvia senza il timeout di about:blank.
