Everything worked fine on the first day I used Antigravity. However, starting the next day, especially when using Claude, I began periodically getting a 400 error during the thinking process. After a certain number of messages, all generations eventually fail with a 403 error.

Sometimes, when I re-login to my account, the first generation triggers the following error:

'Business AI Code API (Staging) has not been used in project seismic-cabinet-pxs3x before or it is disabled. Enable it by visiting https://console.developers.google.com/apis/api/staging-businessaicode.sandbox.googleapis.com/overview?project=seismic-cabinet-pxs3x then retry. If you enabled this API recently, wait a few minutes for the action to propagate to our systems and retry.'

The error resets the next day and generations work again for a while, but after a certain amount of usage, the 403 error returns.
