Actually, the most reliable and consistent fix is this simply:
Close your AG IDE,
Install AG 1.16.5 and run it,
Once you open it, it fetches and reloads your history,
Then reinstall your preferred version, a newer one.
This sequence rehydrates the index so history reappears.
The original application saved global states, extension data, and chat windows under a folder named Antigravity. The new standalone IDE looks for these files under a separate directory named Antigravity IDE.
To fix this, you need to move the underlying VS Code database file (state.vscdb) along with your local storage folder

[Windows] Agent panel shows “No conversations yet” and loses history for all workspaces due to malformed path resolution (//C:/...)
After updating to Antigravity 2.0 on Windows, the Agent panel fails to load any past conversation history associated with workspaces. While the global conversation history is visible, the per-workspace list displays “No conversations yet” under every workspace folder (e.g., C:\WINDOWS\system32, geminifinance, just-dub-it), and the Agent has no access to past context.
This appears to be caused by a path-parsing bug where the IDE passes workspace URIs with a double forward slash prefix (//C:/...) to the language server, which Windows fails to resolve.
The following errors are thrown repeatedly in the language_server.log when trying to resolve workspace paths:
text
E0601 20:33:10.381292 24232 log.go:398] failed to stat uri: CreateFile //C:/WINDOWS/system32: The filename, directory name, or volume label syntax is incorrect.
E0601 20:33:10.381292 24232 interceptor.go:74] /exa.language_server_pb.LanguageServerService/StatUri (unknown): CreateFile //C:/WINDOWS/system32: The filename, directory name, or volume label syntax is incorrect.
The IDE communicates workspace scopes to the Agent’s backend (language_server.exe).
The paths are serialized or resolved into //C:/... (e.g., //C:/WINDOWS/system32) instead of standard Windows paths (C:\WINDOWS\system32) or correct file URIs (file:///C:/...).
Because Windows treats //C:/... as an invalid network UNC path rather than a local file path, the API CreateFile returns an invalid syntax error.
As a result, the database query matching conversation history to the active workspace path fails, rendering the Agent contextually blind to prior workspace conversations.
OS: Windows
Antigravity Version: v2.0.10
Storage Directory Structure:
C:\Users\<user>\.gemini\antigravity\conversations\ (Intact with past .pb/.db files)
C:\Users\<user>\.gemini\antigravity\history.jsonl (Global index matches files, but workspace path comparison fails)
i only needed a specific day chats immediately so i tried [BUG] Chat history lost after Antigravity update - ChatSessionStore index reset to empty - #33 by JC_Caparas the first prompt from here and further prompted for the specific date and got the results
Actually that problem is very different from everyone’s perspective. At first I thought it would work for everyone, but everyone have different levels of it.
Yeah that’s true CheesyCrust. Actually later what I started to do is, I started to maintain a folder with txt fils including all the conversation texts in it and it worked. Anyways, really happy to see it worked for you! Have a nice day.
