[BUG] Google AI Pro mostra 1 semana de espera para Opus no Antigravity + erro "trajectory converted to zero chat messages"

**Olá, sou assinante Google AI Pro ativo, mas no Antigravity estou bloqueado por **1 semana para usar Opus** (e possivelmente outros modelos), o que não bate com as quotas prometidas (reset em 5h).
Além disso, recebo o erro:

  • Trajectory ID: e680a274-4afd-4b94-
  • Error: agent executor error: trajectory converted to zero chat messages

    Testei: nova conversa, prompt curto, logout/login, cache limpo — nada resolve. Isso é um bug de quota ou sync de conta Pro?

Fedora Linux

Aguardo reset de quota e fix. Obrigado!**
