Paid project: Veo 3.1 and Gemini Omni Flash return permission denied

Please review video-model access for Gemini API project gen-lang-client-0224810069.

The project is Paid Tier 1 with active prepaid credit. In AI Studio, a paid API key is selected and Google Drive conversation saving is enabled.

Both video-generation attempts fail:

  • Veo 3.1 Standard: Failed to generate video: permission denied
  • Gemini Omni Flash Preview: Failed to create interaction stream: permission denied

This is a low-volume, legitimate marketing-video test. Could someone review whether the project has a video-model entitlement or restriction and restore access if appropriate?
