7. Google Antigravity Agent shows an empty model list (No Model Selected) and says: Select Model to Send Message Select a model using the model selector in the input box
This usually happens when you have successfully signed in before, and then restart the client later.
The fix is simple: set your VPN to a supported region and enable TUN mode, then restart the Google Antigravity client. After that, the model list should load normally.
