What's Wrong?

Environment

• Claude Code CLI version: 2.1.22 (broken), 2.0.50 (works)
• Claude Desktop App version: Latest (downloaded Jan 29, 2026)
• OS: Windows 10 (Build 10.0.19045.6456)
• Node.js: v20.20.0
• Terminals tested: PowerShell, CMD, Windows Terminal, Cursor integrated terminal

Problem Description

Issue 1: Claude Desktop App - Code tab shows black screen

• Chat tab works fine
• Code tab shows completely black/blank screen
• Shows "Effecting..." but never loads
• Reinstalling doesn't fix it

Issue 2: Claude Code CLI v2.1.x hangs on Windows

• Running claude command shows no output (blank/frozen)
• claude --version and claude --help work
• claude -p "hello" hangs with no response
• Happens in all terminals: PowerShell, CMD, Windows Terminal, Cursor

What works

npm install -g @anthropic-ai/claude-code@2.0.50

Expected Behavior

Claude Code should display the interactive TUI properly on Windows.

Feedback to Anthropic Team

I am a paying customer ($118 USD/month) and I have been struggling with this issue for 2+ days. This has completely blocked my development work.

Problems with this situation:

1. Wasted tokens and usage - I spent significant tokens and API usage just trying to debug this issue that is on Anthropic's side, not mine.

1. Wasted time - Hours of productivity lost troubleshooting a bug that should have been caught before release.

1. No human support - I emailed customer support multiple times. No human has responded. Only an AI auto-reply agent responds, which cannot actually help with technical issues like this.

1. Paying for broken product - I am paying $118/month for a product that doesn't work. The Windows rendering bug has been reported by many users, yet it was still released.

Requests:

1. Please prioritize fixing this Windows rendering bug - it affects many paying customers
2. Please improve customer support - real humans should respond to technical issues
3. Please test on Windows before releasing updates
4. Consider compensating affected users for lost usage/tokens spent debugging Anthropic's bugs

This is frustrating for customers who rely on Claude Code for their daily work.
