I’m experiencing a persistent “Agent execution terminated due to error” issue with Google Antigravity that only occurs on my specific Google account. I’ve tried everything I can think of and nothing has resolved it.
Problem details:
Error appears immediately when trying to use the agent with any prompt
The error occurs with ALL LLM models: Gemini 3 Pro, Gemini Flash, Claude, and GPT - none of them work
I have no MCP servers installed - completely clean setup
The issue is account-specific: When I switch to a different Google account, Antigravity works perfectly fine
My account has the Google AI Ultra plan (paid subscription)
What I’ve already tried: Reinstalled the project multiple times Tested in different folders/directories (works on other accounts, fails on mine) Fixed Windows folder permissions (full control granted) Added folder to Windows Defender exclusions Revoked and reconnected Google Antigravity permissions at https://myaccount.google.com/permissions Cleared browser cache, cookies, and site data Tested in incognito/private browsing mode Tried completely fresh projects in new folders Reset Antigravity preferences in my Google account
Additional observations:
The problem started suddenly yesterday - it was working fine before
Free tier accounts work perfectly with the same setup
API quotas show 0 usage and “unlimited” limits in Google Cloud Console
No errors in browser console (F12 developer tools)
This is extremely frustrating since I’m paying for the Ultra plan but can’t use the service at all, while free accounts work fine. It seems like there’s something corrupted or blocked specifically in my account’s Antigravity configuration.
Has anyone experienced something similar? Is there a way to completely reset my Antigravity account data or clear some hidden cache/state that might be causing this?
Thank you for bringing this to our attention. We have logged this as a bug internally, and our engineering team is working to resolve it as a priority.
Same problem here. I had a week-long block due to quota (which looks like it should have only been 5 hours according to one post), and now my quota is reset it’s completely unusable. I managed to work for about 30 minutes but it was extremely slow, and now it’s bearly replying at all. I also had the error warning that others have reported here, advising to start a new conversation, which I did. I also tried deleting all my past conversations, and logging in and out, but no joy. I’m on the Pro tier, not ultra.
I’m still failing today. with Ultra plan. I have to click ‘Retry’ button almost every one or two minutes. this really sucks and i think Google should at least extend our subscriptions as one solution.
Having the same issue only on my Ultra Workspace account. Been 3 weeks… seems to be an account issue. Contacted via email but haven’t got any response… This is really not acceptable
Can you check the output to see if you’re getting the same errors?
It looks like they don’t have enough servers to handle the traffic - I’m getting these errors hundreds of times during a workday.
Reinstalled the project multiple times
