FlutterFlow Desktop AI Agent setup fails at "Set up the Flutter SDK" with the error "The Flutter SDK download did not complete." The "Prepare the workspace" step also fails as a result, with "Could not prepare the workspace."

Already ruled out:

• Disk space: 171 GB free
• Network/VPN: fails identically on home network and on a mobile hotspot, VPN off
• Norton firewall: confirmed disabled, issue persists
• No partial SDK files left behind in ~/Library/Application Support/FlutterFlow/
• No log file found at ~/Library/Logs/FlutterFlow/

Expected Behavior

The Flutter SDK download should complete successfully during AI Agent setup, allowing the "Set up the Flutter SDK" and "Prepare the workspace" steps to finish without error.

Steps to Reproduce

1. Open FlutterFlow Desktop app on macOS
2. Click into the AI Agent (Beta) setup panel
3. Select "Claude" as the coding agent
4. Confirm "Claude CLI installed", "Signed in to Claude", and "FlutterFlow CLI installed" all show green checkmarks
5. Click "Install required tools"
6. Observe the "Set up the Flutter SDK" step fails with: "The Flutter SDK download did not complete."
7. "Prepare the workspace" also fails afterward with: "Could not prepare the workspace."

Reproducible from Blank

• The steps to reproduce above start from a blank project.

Additional Information

This blocks onboarding entirely — I cannot get past the AI Agent setup screen to use the feature at all. Already spent significant time troubleshooting disk space, network (including testing on a separate mobile hotspot), and firewall settings with no success.
