I am no longer able to use Antigravity on mac since a few hours, i just keep getting “Agent execution terminated due to error.” no matter what i do, no matter which model i choose!
User Tier: Google AI Ultra Subscriber Product: Google Antigravity (Agentic IDE) Impact: Total blocker; unable to generate code or run logic flows.
Issue Description: I am experiencing a persistent error where Antigravity fails immediately upon generation. Despite having an active Ultra subscription and stable internet connection, the agent hangs or errors out regardless of the prompt complexity.
Troubleshooting Steps Already Attempted: I have attempted the following fixes with no success:
Basic Reset: Restarted the physical machine and the Antigravity application.
Authentication: Logged out and re-authenticated fully.
Model Switching: Switched between models; the error persists.
Context Isolation: Disabled all MCP (Model Context Protocol) servers to rule out external tool conflicts. (none were enabled)
Cache Reset: Manually cleared/renamed the local config folder to force a schema refresh.
Current Behavior: The interface accepts the prompt, but the generation phase terminates instantly with a generic error (or hangs indefinitely), returning no output.
Can confirm, been having the same issue all day. AI Ultra for business plan, all models displaying “Agent execution terminated due to error”.
The most critical error appears early in the console logs, stating that the user is not authenticated even though I successfully logged in.
Error Message: “Cache(userInfo): Singleflight refresh failed: You are not logged into Antigravity.”
Consequence: The system failed to set the authentication token. Without this token, the application cannot authorize sessions or access user-specific components.
On my AI Pro account, however, everything seems to work just fine, on the same machine and seconds after logging off my Ultra account.
I’ve been having the exact same issue all day, its so annoying. The output logs say 429 too many requests for my Pro account. When i switch to a non pro Google account, everything works.
Same Problem here. Pro Account not working anymore. Same Error on two different AG installations on two different machines, but with same Pro Account. Free accounts work. Also tried to reinstallation and removing recommended Folders. This is pretty annoying since I paid for this, while free accounts work. Google get into gear - NOW!
This. It’s a little frustrating that you have to pay extra for an Ultra Abo just for Antigravity, and now it’s not working for hours, while it works fine with a free account.
Pro plan here. Not working at all, 0 agents working. I used Antigravity: Reset onboarding and its the same, it doesnt work. Man… we are paying for nothing.
