# How to fix the Chrome 136 error: “No Browser Window is Open” in Leapwork

**Introduction**  
If you're using Google Chrome version 136 with Leapwork and facing the error “**No browser window is open**", this article will help you resolve the issue. Sometimes when you run a test in Leapwork using Chrome, the browser opens, but the test doesn't move forward. This usually **happens when you're using an existing Chrome user profile**.

**The problem is with how ChromeDriver version 136 talks to Chrome. If that Chrome profile is already being used — maybe it has open tabs, background processes running, or extensions installed — it can block ChromeDriver from taking control**. As a result, Leapwork can’t run the test properly because it can't fully control the browser.

**The Solution:**  
The suggested approach is to **create a copy of your existing Chrome profile and use this new profile path in Leapwork**. This avoids the interference caused by active or previously used Chrome sessions.

**Step-by-Step Instructions**  
Follow the steps below to apply the solution:

1. **Close all Chrome instances**  
   - Ensure no Chrome windows are open before proceeding.

2. **Copy your existing Chrome profile**  
   - Open PowerShell ISE (search for it in the Start Menu).
   - Run the following command to copy your default Chrome profile to a new location:  
     _Copy-Item "$__env:LOCALAPPDATA\\Google\\Chrome\\User Data\\Default" "C:\default\_profile" -Recurse -Force_  
   - Wait for 1–2 minutes until the process is complete.

3. **Update Leapwork browser settings**  
   - Open Leapwork Studio.  
   - Navigate to the Chrome browser settings.  
   - Enable the “**Use Existing Profile**” option.  
   - Enter the following path:_C:\default\_profile\Default_

By using a copied Chrome profile, you can successfully fix the issue and continue executing your browser flows in Leapwork without interruption.
