When I was on v0.4.35, codex properly runs on WSL but on the later versions I get the image above.

What steps can reproduce the bug?

On a Windows machine without Ubuntu,

  1. wsl.exe --install -d Debian --no-launch
  2. Open Debian terminal
  3. curl -o- https://raw.githubusercontent.com/nvm-sh/nvm/master/install.sh | bash
  4. nvm install 22
  5. npm i -g @openai/codex
  6. codex
  7. install v0.4.35 of the VSCode extension
  8. The extension works through the Debian WSL!
  9. Install latest version of the VSCode extension
  10. The extension now doesn't work!

What is the expected behavior?
