Bug: chat history disappears after restart but .pb files still exist

Google Antigravity
1

macOS Apple Silicon

Problem:
My Antigravity chat history disappears after quitting the app or restarting the Mac, but the local conversation files still exist in:
~/.gemini/antigravity/conversations/

What I observed:

  • repositories/projects are still there
  • conversation .pb files remain on disk
  • chat history UI is empty after restart

Versions tested:

  • 1.20.5
  • 1.19.6
  • 1.16.5

What I tried:

  • restarting Antigravity
  • restarting macOS
  • reopening folders/workspaces
  • reinstalling over the existing app
  • downgrading versions
  • clearing non-conversation UI/index state

Result:
No version restores the chats in the UI.

Evidence:
I can provide screenshots of the empty history UI and terminal output showing the .pb files still present in ~/.gemini/antigravity/conversations/

Current conversation files visible on disk include examples like:

  • 413c368e-9fb9-47b9-a74b-8115eb78c5ff.pb (about 25 MB)
  • cb2e52bf-289b-41c2-9788-33b306453a2b.pb (about 23 MB)
  • dd83b5dc-f459-4f45-83d1-6a991be29ec9.pb (about 9 MB)
  • 7261f65a-e796-4697-a309-b3a404fa2f90.pb (about 6 MB)

This appears to be a conversation indexing/history display failure rather than actual deletion.
