Google's Antigravity IDE, the company's AI-powered development environment, is experiencing significant stability problems on Windows 11, with users reporting startup crashes, blank login screens, and missing interface elements. The issues stem from version conflicts between separate Antigravity applications, incorrect installation permissions, and corrupted user data files that prevent the IDE from functioning properly.

Why Is Antigravity IDE Failing on Windows 11?

The root causes of Antigravity IDE failures on Windows 11 are multifaceted and often interconnected. Google has split its offering into two separate applications: the standard Antigravity app for non-coders and the Antigravity IDE for developers. When both are installed simultaneously, they can overwrite each other's files, creating version conflicts that destabilize the entire system. Additionally, running the installer with full administrator rights can disrupt the OAuth token handoff, which is the authentication mechanism that allows users to log in with their Google accounts. For Windows-specific environments, certain bugs such as the language server pointing to an internal staging server can also prevent core functionality from working as intended.

Beyond installation issues, corrupted user data files and configuration errors frequently trigger crashes. A single corrupted conversation file can cause the entire IDE to crash on launch, making the application unusable until the problematic file is isolated and removed.

What Are the Most Common Antigravity IDE Problems?

Users encountering issues with Antigravity IDE on Windows 11 typically experience one or more of the following problems:

• Startup Crashes: The IDE fails to launch or crashes immediately upon opening, often due to corrupted core files or version conflicts between the main app and the IDE.
• Blank Login Screen: The "Sign in with Google" button becomes unresponsive, preventing users from authenticating and accessing the development environment.
• Missing Interface Elements: The code workspace fails to appear after login, indicating that the wrong version of the application was installed or core interface files are corrupted.
• Stability Issues During Execution: The IDE freezes or crashes when running certain features, particularly when the agent executes Linux commands through Windows Subsystem for Linux (WSL).

How to Fix Antigravity IDE on Windows 11

Google and Windows support communities have documented several effective troubleshooting steps that resolve most Antigravity IDE issues on Windows 11:

• Perform a Clean Reinstall: Completely uninstall Antigravity IDE, delete all related folders from %APPDATA% and the user profile directory, then download and reinstall the latest version from the official website. During installation, select the "Just Me" option to avoid permission conflicts. This approach resolves version conflicts and repairs corrupted core files by removing all installation traces before setting up the IDE with correct permissions.
• Fix the Google Sign-In Issue: Create a new local Windows user account, set Google Chrome as the default browser, install Antigravity IDE to a shared system folder at C:\ProgramData\Antigravity, and complete the initial setup. Then log back into your main Windows account, where the IDE should now function correctly. This workaround bypasses the broken OAuth token handoff that prevents authentication.
• Restore the Missing Interface: Uninstall both the standard Antigravity app and the IDE, then visit the official Google Antigravity website and download only the Antigravity IDE version. Install the IDE first and allow it to complete its setup before optionally installing the standard app. This ensures you have the correct developer version with all necessary interface components.
• Isolate Corrupted Conversation Files: Close the IDE completely, navigate to %USERPROFILE%\.gemini\antigravity\conversations, create a new folder named _quarantine, and move the most recent conversation folder into it. Reopen the IDE to test if the crash persists. If it does, continue quarantining older conversations until you identify the corrupted file, then delete it permanently.

For users seeking a complete reset, deleting the main configuration folders at %USERPROFILE%\.antigravity and %APPDATA%\Antigravity, followed by a fresh reinstall, removes any corrupted settings and cache while preserving code projects.

Is Antigravity IDE Stable Enough for Production Use?

Antigravity IDE does support Windows 11 64-bit and Windows 10 systems, and the application is available across Windows, macOS, and Linux platforms. However, some users have experienced stability issues including freezes and problems with certain features, particularly when the agent runs Linux commands in WSL. For the best performance and stability, Google recommends using the dedicated Antigravity IDE for developers rather than the standard app designed for non-coders. The distinction between these two applications is critical; installing the wrong version or both simultaneously is a primary cause of the failures users are experiencing.

The prevalence of these issues suggests that while Antigravity IDE is a powerful AI-powered development tool, Windows 11 users should be aware of potential stability challenges and follow proper installation procedures carefully. Ensuring correct permissions, avoiding administrator-level installation when not necessary, and maintaining separation between the IDE and standard app versions are essential for reliable operation.
