Antigravity chat is unresponsive since April 19 on Windows 11

Hello,

I’m experiencing an issue with Antigravity chat.

Since April 19, 2026, when I type a message in the chat and send it, nothing happens.
There is no response and no visible error message.

Environment:

  • OS: Windows 11

  • Platform: Antigravity desktop app

  • Date issue started: April 19, 2026

  • Scope: all chats

Steps to reproduce:

  1. Open Antigravity

  2. Open a chat

  3. Type a message

  4. Send it

  5. No response is returned

What changed before this issue:
I did not intentionally change settings or configuration before this started.

What I already tried:

  • Restarted Antigravity

  • Restarted my PC

  • Tried other chats/workspaces

Could you confirm whether this is a known issue or account-specific issue?

Thank you.

I’ve posted the fix here IT’S WORKING - Antigravity AI Chat Models - Google Antigravity - Google AI Developers Forum

Fixed by rolling back to version 1.19.5(it’s stable for me) on Windows 11. The Chat now responds normally

I reverted to 1.22.2 and it worked for me. The poison appears to be in 1.23.2.

Gotcha!! Just delete the .git of the folder in which you are working, chat responds normally then
