AI Studio stuck on “Preparing system resources” after Google Drive migration (Gemini 3.1)

Hello,

After accepting the Google Drive to AI Studio storage migration, my projects are no longer working properly.

Issues I am experiencing:

  • Stuck on “Preparing system resources…”

  • “Failed to load app”

  • Gemini 3 Flash/Pro Preview stays on “Running” for 500+ seconds

  • Preview does not load

  • Even new projects do not generate output

  • Same issue occurs on another Google account

My code files are still visible, but the build/preview system does not work.

Is this a known issue related to Gemini 3.1 rollout or storage migration?

Thank you.
