Critical Issue in Antigravity 2.0 - Completely Unusable for Pro Subscriber

[kukie-yiqing]

Hello Support Team,

I am currently experiencing a critical and persistent issue with the latest Antigravity 2.0. Every single prompt I submit immediately triggers an error. Even after clicking "retry" more than ten times, the system returns the exact same failure.

As a paying Pro subscriber, this is completely unacceptable. This ongoing outage is severely disrupting my workflow and entirely depriving me of the premium service and rights I am paying to enjoy.

Please investigate and resolve this capacity issue immediately. My debug log is attached below for your reference:
