[BUG] WS client disconnected

[bertsons]

Environment

• Platform (select one):
  • Anthropic API (I am just using Claude Code integration in VS Code, I imagine this uses Anthropic's API).
• Claude CLI version: 1.0.30 (Claude Code)
• Operating System: Ubuntu 24.04
• Terminal: Claude Code tab in VS Code

Bug Description

I was using Claude Code in VS Code, and it suddenly crashed. It's a small project (no more than ~3K lines). I rejected a request for code change and then it went off and started thinking again, then the Claude Code tab closed itself. See the logs down below. The crash happened at 17:18:19.189 ("WS Client Disconnected").

Steps to Reproduce

No idea. This is intermittent, and has only happened once.
