ERROR: Model produced a malformed edit that the agent was unable to apply

In antigravity with gemini 3 flash, I’m often getting “Error while editing: Model produced a malformed edit that the agent was unable to apply.”
That is, when I’m lucky and there’s no error “Agent execution terminated due to error. Model capacity reached, try again later”.

This platform is completly unusable as it is now, even for the most simple things.

i got a same error since yesteday
