Codex desktop app crashes on Windows x64 after Codex Micro / serialport path is triggered

Summary

Codex desktop app on Windows x64 crashes when switching/opening conversations. This appears to match #33409 / the serialport.node / Codex Micro gate issue.

No dump is attached because full process dumps may contain sensitive memory. Below is the WinDbg stack summary only.

Environment

• OS: Windows x64, build shown in dump as 10.0.26100.1
• App package: OpenAI.Codex_26.707.9981.0_x64__2p2nqsd0c76g0
• Process: ChatGPT.exe
• App process version in dump: 150.0.7871.115
• System Node after upgrade: v26.4.0 / npm 11.17.0

Timeline / behavior

• The app was updated yesterday.
• Crashes started today when switching/opening conversations.
• I later uninstalled and reinstalled the app today, so the current package install timestamp only reflects the reinstall, not the original update time.
• Reinstalling did not fix the issue.
• Upgrading the system Node.js did not fix the issue.
• Fresh crash dumps after reinstall still show the same failure in the bundled native module.

Current assessment

This does not look like a broken local install, system Node.js issue, node_repl MCP issue, or missing Windows runtime dependency. It looks like the app package contains an old native serialport.node that is incompatible with the Electron/Node runtime path that gets activated by the Codex Micro / Work Louder integration.

A server-side feature flag / Statsig gate activation may explain why the app update happened earlier but the crash started later.
