Background
The issue started after receiving the “This version of Antigravity is no longer supported” warning. I updated to the latest version (downloaded today from the official source), but the problem persisted.
What’s happening
When I open my project folder in Antigravity and send any message to the LLM:
- There is no response at all
- The usual progress indicators (“Thinking”, “Generating”, etc.) never appear
- It looks like the request is not even being processed
What I’ve tried
- Updated Antigravity to the latest version
- Reproduced the issue on two separate machines: one Windows PC and one Mac — same result on both
- Opened a different, unrelated folder in Antigravity → LLM works perfectly
- Opened the exact same problematic repository in another IDE (Codex) → works without any issues
Project details
- Mobile app project (Expo / React Native)
- The repo itself is functional and has no known corruptions
Conclusion
Since the problem follows the repository across two different operating systems and two different machines, but does not occur in other folders or other IDEs, I suspect something inside the project directory is causing Antigravity to silently fail — possibly a config file, a hidden file (e.g. .gemini/, GEMINI.md), an oversized file inflating the context window, or something in the project structure that Antigravity can’t handle.
Questions
- Are there any known project-level files or configurations that can cause Antigravity to silently stop processing requests?
- Is there a way to see debug logs or error details when the LLM is unresponsive?
- Could the initial “unsupported version” warning have left behind a corrupted cache or config tied to this project?
Any help appreciated. Happy to share more details or run diagnostics if needed.
