Hi @mojoxd,

Welcome to the Forum.

Please check the following in **Antigravity IDE (v2.5.5)**:

1. **Check Browser Tools & Strict Mode in Settings ([Browser Overview](https://antigravity.google/docs/ide/browser/#core-mechanisms) & [Settings Docs](https://antigravity.google/docs/settings/#strict-mode)):**

2. **Quit Existing Chrome Windows & Enable Remote Debugging ([Separate Chrome Profile Docs](https://antigravity.google/docs/ide/separate-chrome-profile/)):**

3. **If You Are on Windows (Check `$HOME` for Playwright):**

If the browser still does not launch on **v2.5.5** , please share:

- Your **OS** (Windows, macOS, or Linux) and **Chrome version**.
- Either a **screenshot of the error** on the failed Browser step in the chat panel, or the **diagnostic logs (`.txt` file)** from **Help \> Toggle Developer Tools \> Console**.
