What Should Happen?

Cloud Code should be able to run the prompts. Currently it just can't do anything, it exits every time and crashes.

Error Messages/Logs

Steps to Reproduce

I cannot use /bug, /doctor, or any

Claude Code commands because the extension crashes within 2-3 minutes of

starting VS Code - before I can type any commands.

The crash happens automatically during extension initialization (no user

interaction needed). The extension is completely unusable.

Key points:

• Cannot run /bug command (extension crashes before I can use it)

• Cannot run /doctor command (same reason)

• Already uninstalled the extension completely (only way to stop crashes)

• macOS crash reports show SIGABRT in Node.js worker thread (Thread 12)

• 100% reproducible - tested 6+ times

I've attached three files with complete technical analysis:

1. Detailed bug report with root cause (Node.js

worker::MessagePort::OnMessage crash)

1. Full investigation timeline

1. macOS crash report showing the exact call stack

This needs to be escalated to your engineering team as it's a critical bug

making v2.0.35 completely unusable on macOS Apple Silicon.
