What's Wrong?

I am using Claude Code and that too it's Claude Max Plan and working on it since last 3-4 months...But suddenly since last 2-3 days application started hanging pretty frequently, almost in every 2-3 conversations ...Below are the details of my conversation

Here's what you can include in the GitHub issue:

---

Environment

• Claude Code version: CLI (Windows desktop)
• Model: claude-opus-4-6 (1M context)
• OS: Windows 11 Pro 10.0.26200
• Node: v20.20.0
• Shell: bash

Conversation details

• Duration: ~2-3 hours continuous session
• Message count: ~50+ back-and-forth turns
• Files modified: ~12 files across a monorepo (Prisma schema, NestJS controllers/services, React components/pages)
• Tool calls: Heavy — Read, Edit, Write, Bash, Grep, Glob, Agent (subagents), TodoWrite, AskUserQuestion used extensively
• Context pressure: Very high — multiple full-file reads of 500-1000+ line files, many large Edit operations

Hang behavior

• Frequency: 3-4 times during this session
• When it happens: Mid-response, typically during or just before an Edit tool call on a large file
• Symptoms: Response stops completely — no streaming output, no tool call progress. Appears frozen.
• Ctrl+C behavior: Sometimes works to interrupt and resume with "continue", sometimes does not respond at all
• Recovery: Had to restart Claude Code CLI and say "continue from where you left off"
• Pattern: Seems to correlate with conversation length — hangs became more frequent as the session progressed (no hangs in first 30 min, multiple in last hour)

Workaround

• Starting a new conversation resolves the issue temporarily
• Shorter conversations with fewer file reads seem stable
