[BUG] Interactive TUI hangs after trust prompt on Windows -- regression between 2.1.58 and 2.1.69

What's Wrong?

After selecting "Yes, I trust this folder" at the workspace trust prompt, Claude Code hangs indefinitely. The checkmark appears next to the selection but the REPL never loads. No error message, no output, no debug logs. The freeze is so severe that Ctrl+C does not terminate the process. force-quitting via Task Manager is required. Non-interactive mode (claude -p "...") works perfectly -- this is isolated to the interactive TUI.

Manually downloading the 2.1.58 binary and replacing claude.exe immediately fixes the issue. As soon as auto-update pulls a newer version, the hang returns.

What Should Happen?

After selecting "Yes, I trust this folder," the interactive REPL should load and accept input.

Error Messages/Logs

No error messages or logs produced. stderr redirect (`claude 2> err.txt`) produces an empty file. `$env:CLAUDE_CODE_DEBUG="1"` produces no log files in `~/.claude/logs` or `$env:TEMP/claude`. `claude doctor` passes all checks. `claude auth status` shows logged in with Max subscription.

Steps to Reproduce

1. Install Claude Code 2.1.69 on Windows via native installer (irm https://claude.ai/install.ps1 | iex)
2. Open any terminal (PowerShell 7.5.4, cmd.exe, or Git Bash — all affected)
3. Navigate to a git-initialized directory
4. Run claude
5. Select "Yes, I trust this folder"
6. Observe: checkmark appears, then nothing. Hangs indefinitely.

Ruled out as causes:

• No .mcp.json files anywhere (verified with recursive search)
• Hang persists with entire ~/.claude/ directory renamed (fresh config)
• Hang persists in a brand new git init directory
• Reproduced in PowerShell 7.5.4, cmd.exe, Git Bash, and pwsh -NoProfile
• claude -p "say hello" works fine (API/auth confirmed working)
