Interactive mode freezes on Windows 11 (v2.1.31 native installer)

Bug Description

Claude Code v2.1.31 (native installer) freezes in interactive mode on Windows 11. The TUI opens, shows the prompt, but does not respond to any input. The -p (print) mode works correctly, confirming the API connection is functional.

Environment

• OS: Windows 11 (10.0.26200.7705)
• Claude Code Version: 2.1.31 (native installer)
• Install Method: Native (claude install)
• Terminal: Windows Terminal (both CMD and PowerShell affected)
• Plan: Claude Max (Opus 4.5)

Steps to Reproduce

1. Install Claude Code v2.1.31 via native installer
2. Navigate to a project directory
3. Run claude
4. TUI opens normally with logo and prompt
5. Type any text and press Enter
6. No response - the interface is frozen

Diagnosis Performed

• claude -p works (non-interactive mode is functional)
• claude doctor passes all diagnostics
• Removed all MCP servers - still freezes
• Used --no-chrome flag - still freezes
• Used --setting-sources user - still freezes
• Killed all background claude.exe processes - still freezes
• Tested on both CMD and PowerShell - both affected
• Downgraded to v2.1.19 (stable) - works consistently

Workaround

Downgrading to v2.1.19 stable resolves the issue:

claude install stable

Additional Context

• Freeze is intermittent but occurs ~80% of the time on v2.1.31
• Multiple stuck claude.exe child processes found in Task Manager
• Related issues: #7171, #6823

Expected Behavior

Interactive TUI should accept input and respond consistently on Windows 11.

Actual Behavior

TUI opens but does not process any keyboard input.
