What's Wrong?

Description
After the latest desktop app update, SSH sessions stop responding to messages.
Claude connects to the remote machine successfully but never replies to any input.
The session just hangs indefinitely.

Steps to reproduce

1. Open Claude Code desktop app on Windows
2. Create new session with SSH environment
3. Type any message and send
4. Claude shows "thinking" for 1 second then freezes

Expected behavior
Claude responds to messages normally

Actual behavior
Claude connects to SSH host but never responds.
Messages accumulate with no replies.
Error shown: "SSH sessions cannot be teleported to the cloud"

Workaround
Running claude directly via PuTTY SSH terminal works fine.

Environment

• OS: Windows 10
• App version: Claude Code Desktop (latest)
• SSH host: Linux VPS (Ubuntu)
