You are seeing Antigravity refuse setup with an account error and Gemini Code Assist calls failing with a 403. The key is that Gemini has been disabled on your account for a Terms of Service violation, which only Google can reverse.
Gemini disabled error 403 in Antigravity IDE and Code Assist
You try to sign in to Antigravity IDE and get: “There was an unexpected issue setting up your account. We apologize for the inconvenience. Please try again later.” The IDE asks you to sign in with a different account.
At the same time, Code Assist features fail with: “Cloud Code Assist API error 403: Gemini has been disabled in this account for violation of Terms of Service.”
If your symptom is quota exhaustion rather than a disablement, check this quick explainer on quota limits in Antigravity.

2. Send an appeal to the Gemini Code Assist team
This is the official route for disablement reviews.
Send an email that includes your account, region, timestamps, screenshots, a short description of your use, and your commitment to comply.

Hello Gemini Code Assist team,
My personal Google account ([your Gmail address]) is receiving:
Antigravity IDE: “There was an unexpected issue setting up your account. Please try again later.”

Intended use: personal development and learning
No automation or prohibited content to my knowledge
Region: [your country]
Browser: [name and version]
Antigravity workspace or project name if any: [optional]
Attached: screenshots and a HAR network log of the failed sign in
I am committed to following all Terms of Service and acceptable use policies. Please review my account and advise on restoring access or any steps needed for compliance.
Thank you,

3. Attach helpful diagnostics
Screenshot the Antigravity error and the 403 response from your IDE or browser devtools.
Optional but helpful: capture a HAR file from Chrome
– Open Antigravity, press F12, open the Network tab, enable Preserve log, reproduce the error, right click in Network and choose Save all as HAR with content. Guide: Capture HAR with Chrome DevTools.
4. Verify basic account prerequisites
You must be in a supported region for Gemini Code Assist. See the product overview: Gemini Code Assist overview.
If you need immediate continuity, sign in with another Google account that has not been disabled for Gemini Code Assist and is policy compliant. Keep usage within acceptable use guidelines.
Continue with Gemini on the web
You can still access the Gemini web experience for research while the IDE integration is under review. Avoid content or patterns that could violate policy.
Workspace admin review
For managed accounts, ask your admin to review organizational policies. They may need to re enable access or confirm no domain level blocks exist.
Sign out of all Google accounts in the browser, clear cookies for antigravity and google domains, then sign in with the affected account only.
Try a clean browser profile or an incognito window with extensions disabled to rule out blockers.
Ensure your system clock and timezone are correct.
Confirm the same account can still access standard Google services. Note that this disablement can apply only to Gemini Code Assist and Antigravity, not the entire account.
If you receive a response requesting more details, reply to the same email thread and attach the requested logs or screenshots.
Best Practices
Follow the acceptable use policy for generative AI and Code Assist at all times. Review: AI use policy.
Avoid bulk unattended code generation or scraping, and never submit disallowed content.
Keep one personal account for personal use. Do not share credentials or drive automated traffic from shared machines.
Monitor rate and capacity limits to avoid noisy retries. If you keep running into ceilings, review these notes on Antigravity quota behaviors.
Final Thought
The 403 message means Gemini features were disabled for policy reasons on your account. Only the Gemini Code Assist team can restore access, and the fastest resolution is a clear, complete appeal email with timestamps, screenshots, and a short compliance statement.
