What's Wrong?

Hello team,

I want to run Claude Code (v2.0.37) through Sandboxie in a Sandboxing environment on Windows. However, it crashed due to EPERM issue when invoking setRawMode. The keyboard input is fully broken, so there's no any interaction working.

What Should Happen?

Claude Code can successfully run in Sandboxie environment on Windows, accept user inputs as prompts, similar to Gemini CLI in Sandboxie.
