Codex frequently freezes and becomes unresponsive on Windows 11 after updating to the latest version

After updating Codex to the latest version, the application frequently freezes and becomes unresponsive on Windows 11.

The issue occurs repeatedly during normal use. In many cases, Codex becomes unresponsive immediately after I submit a new prompt in the conversation window. It may also freeze while it is processing or reasoning about a request.

When the issue occurs, the application responds very slowly or stops responding entirely. I also frequently see the reconnecting or retry icon appear repeatedly, even though my network connection is stable and other applications can access the internet normally.

This problem has significantly affected the usability of Codex. Since the latest update, the application freezes so frequently that it is difficult to use for normal development work.
