Cannot input or paste @ sign in Codex CLI terminal on Windows

What version of Codex is running?

0.41.0

Which model were you using?

gpt-5-codex

What platform is your computer?

Microsoft Windows NT 10.0.26100.0 x64

What steps can reproduce the bug?

When using Codex CLI, I cannot enter the @ character in the terminal.

If I try to type @ (e.g., for referencing files with @), nothing happens.

If I paste text containing @ (e.g., an email address like test@example.com), the @ sign is removed and only testexample.com appears.

This makes it impossible to reference files with @ or use commands/strings that contain it.

Steps to reproduce:

Open Codex CLI.

Try to type @ directly into the terminal.

Or paste an email address (e.g., user@example.com).

What is the expected behavior?

@ should appear as typed or pasted.

What do you see instead?

@ is ignored/stripped out completely.
