TL;DR

Reverting to a previous version of the Codex App or checking for updates that may address compatibility issues with GPT5.5 might resolve the hangs, unresponsiveness, and crashes.

Guidance

  • The issue seems to be related to the update to GPT5.5, so checking the Codex App's documentation or support channels for known issues or updates regarding GPT5.5 compatibility might provide insights.
  • Given that the user is working in WSL (Windows Subsystem for Linux), there could be environment-specific issues; trying to run the Codex App natively on Windows or checking for WSL compatibility might help isolate the problem.
  • Since the problem started after updating to GPT5.5, reverting this update or seeking guidance on how to properly configure GPT5.5 with the Codex App could be a viable workaround.
  • Reviewing system logs or application logs for specific error messages related to the crashes (Code=9, Signal=Null) might offer more detailed clues about the root cause.

Notes

The provided information does not specify how GPT5.5 was integrated or updated, which could be crucial for diagnosing the issue. Additionally, the role of WSL in the setup might introduce unique compatibility challenges.

Recommendation

Apply workaround: Given the immediate need for a functional Codex App, reverting to a previous version or seeking a compatibility update for GPT5.5 seems like the most straightforward path to resolving the issue, assuming such an update or previous version is available and compatible.
