How to fix Antigravity server crash on Windows 10 WSL?

I am currently encountering the error:
“Antigravity server crashed unexpectedly. Please restart to fully restore AI features.” when working with WSL on Windows 10.

Whenever I start WSL together with Antigravity, the error “Antigravity server crashed unexpectedly. Please restart to fully restore AI features.” always appears. The Agent Sidebar shows “Authentication Required” (as shown in the image), and I am unable to click the “Sign Out” button.

However, when I completely shut down WSL using the command wsl --shutdown and then restart Antigravity, the AI module works normally again.

Environment:

  • Antigravity Version: 1.20.6 (also met on old version)

  • OS: Windows 10 Pro

  • WSL version: 2.6.3.0

  • CPU: Intel Xeon E5-2699 v3

  • RAM: 64 GB

What I have tried:

  • Reinstalling Antigravity

  • Deleting the folder \AppData\Roaming\Antigravity

  • Removing the .antigravity-server and .gemini directories inside WSL
