Antigravity IDE 2.5.2 freezes when opening a workspace on Windows 11

Hi everyone,

I’m having a serious freezing problem with Antigravity IDE on Windows 11.

Whenever I open a workspace, the editor becomes unresponsive after a short time. It sometimes recovers after a while, but then the IDE becomes unusable.

This happens with more than one project. For example, I tested two unrelated workspaces, and both of them work normally in Cursor.

My environment:

  • Windows 11 x64
  • Antigravity IDE 2.5.2
  • VSCode OSS 1.107.0
  • Electron 39.2.3
  • Chromium 142.0.7444.175
  • Node.js 22.21.1

I have already tried:

  • Reinstalling Antigravity several times
  • Creating a new user-data directory
  • Starting with --disable-extensions
  • Starting with --disable-gpu
  • Disabling Git
  • Excluding .git, build folders, log folders, and other large directories
  • Testing different workspaces

The problem still happens with a clean profile, no extensions, and GPU acceleration disabled.

The log contains:

CodeWindow: detected unresponsive

In some tests I also saw:

No ptyHost heartbeat after 6 seconds

I also noticed these messages during startup:

OverrideStoreLifecycle
OAuthTokenLifecycle
SidebarWorkspacesLifecycle
ArtifactReviewLifecycle

Could this be related to the built-in Agent/Workbench initialization or state synchronization?

Has anyone else experienced the same issue on Windows? Is there a known workaround or an official fix planned for the IDE version?

Hi @HonWu, Welcome to the Forum!

If you are still using an older release of Antigravity, we highly recommend updating to our latest IDE version, 2.5.5. This update resolves many of the previously known bugs and significantly improves the overall stability and performance.

Could you please update your application to version 2.5.5 and check if your issue is resolved?

If you continue to encounter unexpected behavior after the update, we strongly encourage you to submit a report using the built-in Provide Feedback feature (located via the Feedback icon in the top-right corner of the interface).

I have updated to v2.5.5 as suggested, but the issue persists. CodeWindow: detected unresponsive still occurs when opening workspaces with a clean profile.
