"Agent terminated due to error..." is a problem

Google Antigravity
1

Antigravity isn’t working.

When I send a message to the antigravity chat, I always get this error:
‘’’
Our servers are experiencing high traffic right now, please try again in a minute.
‘’’
But I don’t have this problem on my other personal account.

The issue is related to my work account.

I have a PRO subscription.

I’ve tried a lot of things already:

  • Switching from my work account to my home account. It works on my home account, but not on my work account.
  • Reinstalling Antigravity.
  • Waiting for a few minutes, hours, or a day.
  • It’s the same on every model (Gemini, Claude).
  • Restart the computer.
  • A different operating system.
  • And a few other things…

Please fix this.

I wrote to Google One support. They told me to update the app or restart my computer. That’s ridiculous
