Antigravity recent versions completely broken on Windows 11 on ARM64 and cannot downgrade

Google Antigravity
1

I am a AI Pro user on Windows 11 on ARM64.
I was happily using a older version of Antigravity and Google forced me to upgrade to the latest by disabling the older versions. I have tried all of the newer versions of Antigravity (made upgrade manual) that are still supported and none of them work on Windows 11 on ARM64. Tried 1.19.6, 1.19.5, 1.19.4, 1.18.4 and 1.18.3. All the older ones are no longer supported.

Simply typing a single command to the agent, hangs the UI and after a few mins requests a restart of antigravity. At this point I have no way to use Antigravity.

Hi @iunknown ,

Welcome to the Forum!
Thank you for flagging the issue. Since this affects every release from 1.18.3 to 1.19.6 on Windows 11 ARM64, it indicates a platform-specific issue rather than a bug in the latest version.
If you’re using ARM64, could you try installing the x64 version and running it under Windows to see if the issue persists?
Please try:

  • Fully uninstall Antigravity
  • Delete the remaining config/cache folders (if any)
  • Reboot
  • Install the latest version (1.19.6) fresh

Hi @Mrinal_Ghosh

Thank you for your response. I was experimenting with different versions of Antigravity and 1.18.4 suddenly seemed to work with Windows 11 on ARM64. This had not worked the first time I had tried it. Not sure what went wrong the first time or why it worked the second time. Putting my working version details here in the hope that it might help others who may be facing the same issue.
