What's Wrong?

I work on both windows (WSL2) and macOS at home. When switching back to my windows machine and trying to update claude code to the newest version (v2.0.x) it no longer worked and froze at the terminal stage before the TUI launched.

Environment
WSL 2: Ubuntu 22.04.5 LTS (jammy)
Terminal: bash
Node.js: v24.4.1 (via NVM)
npm: 11.4.2

What's happening
I work between two computers - macOS and Windows (WSL 2). When switching back to my windows machine and trying to update claude code to the newest version (v2.0.x) it broke completely. When i run claude in my desired project dir, I get a hanging cursor and it never lanuches the TUI.

I tested every version systematically to find where it breaks:

Versions tested:
Working in WSL:

• v1.0.44 ✓
• v1.0.46 ✓
• v1.0.55 ✓
• v1.0.56 ✓ (last working version)

Broken in WSL:

• v1.0.57 - hangs with blinking cursor before UI loads, Ctrl+C works
• v1.0.60 - hangs with blinking cursor before UI loads, Ctrl+C works
• v1.0.65 - hangs with blinking cursor before UI loads, Ctrl+C works
• v1.0.85 - UI loads then freezes, Ctrl+C doesn't work
• v1.0.100 - UI loads then freezes, Ctrl+C doesn't work
• v2.0.0 - hangs with blinking cursor before UI loads, Ctrl+C works
• v2.0.10 - hangs with blinking cursor before UI loads, Ctrl+C works

What Should Happen?

Claude Code should start up normally like it does in v1.0.56 and enter the TUI welcome or continue view.
