Hey, thanks for the report. “Stuck thinking” issues often relate to network configuration or extension conflicts. Let’s gather some diagnostic info:

Please share:

  1. Network diagnostics: Go to Cursor Settings > Network > Run Diagnostics and screenshot the results.
  2. Request ID: After Gemini gets stuck, click the chat menu (top right) > Copy Request ID.
  3. Extension check: Try running cursor --disable-extensions in your terminal/CMD to see if Gemini works without extensions.

Quick fixes:

  • New chat: Start a fresh chat session. Similar model launch issues were resolved this way.

Network diagnostics will help determine if this is a network/proxy issue or something else. Let me know what you find.
