What's Wrong?

After auto-updating to 2.1.84, Bash permission prompts for network commands (scp, ssh) no longer work. A terminal window briefly flashes open then closes before I can approve or deny. The command is silently rejected. This worked correctly in previous versions.

What Should Happen?

Terminal stays open showing the permission prompt, user can approve/deny.

Error Messages/Logs

Terminal opens and immediately closes. Permission silently denied.

Steps to Reproduce

Run Claude Code VSCode extension v2.1.84 on macOS (Apple Silicon)
