• Type: Fatal Dependency Injection Error / Extensions Marketplace Failure
Problem Description
After upgrading to Antigravity 2.0, the built-in AI Agent Manager and the Extensions Marketplace completely stopped working. The IDE keeps throwing an Unexpected HTTP response: 429 error when trying to fetch extension manifests, accompanied by an endless cycle of critical Window log crashes.
Even after performing a 100% clean installation (manually wiping ~/Library/Application Support/Antigravity IDE, clearing ~/.antigravity, and purging the cache folders), the core Dependency Injection container reliably crashes upon startup because the system cannot find the agentSessions service required by the aae (Antigravity Agent Environment) component.
Steps to Reproduce
-
Perform a clean install of the latest Antigravity IDE on macOS.
-
Launch the IDE and try to access the “Build with Google” setup screen or install any plugin.
-
Open the Output view and switch the log output channel to “Window”.
-
Observe the fatal DI error loop and menu item reference command failures.

Impact
This issue completely breaks the core feature of the Antigravity platform, transforming the IDE into a basic text editor with zero functional agent capabilities or plugin integrations. Clearing caches or resetting settings.json provides no resolution, indicating that the agentSessions module is either missing or misconfigured directly inside the distributed workbench.desktop.main.js build.
Please address this dependency coupling issue as soon as possible.
