What version of the Codex App are you using (From “About Codex” dialog)?

26.601.2237.0

What subscription do you have?

ChatGPT Plus

What platform is your computer?

Microsoft Windows NT 10.0.22631.0 x64

What issue are you seeing?

Browser and Computer Use plugins became unavailable in the Codex desktop app.

In Settings > Browser, it shows:
应用内浏览器插件不可用

In Settings > Computer Use, it shows:
Computer Use 插件不可用

Both plugins were available yesterday, but today they are unavailable after opening Codex. Restarting Codex does not fix it.

What steps can reproduce the bug?

  1. Open Codex desktop app on Windows.
  2. Go to Settings > Browser.
  3. Browser shows “应用内浏览器插件不可用”.
  4. Go to Settings > Computer Use.
  5. Computer Use shows “Computer Use 插件不可用”.
  6. Restart Codex.
  7. The two plugins are still unavailable.

What is the expected behavior?

Browser and Computer Use should be available. They were working yesterday, but today they are both shown as unavailable.

Additional information

Local checks:

  • The plugin files still exist locally:

C:\Users\lenovo\.codex\plugins\cache\openai-bundled\browser\26.601.21317
C:\Users\lenovo\.codex\plugins\cache\openai-bundled\computer-use\26.601.21317

  • config.toml has both plugins enabled:

[plugins."browser@openai-bundled"]
enabled = true

[plugins."computer-use@openai-bundled"]
enabled = true

  • The installed Codex app resources also contain browser and computer-use plugins.
  • After restart, .codex-global-state.json keeps only:

electron-chrome-extension-sync-managed-plugin-ids: ["chrome@openai-bundled"]

  • Browser and Computer Use were available yesterday, then became unavailable today without me changing settings.

I am seeing the same issue on Windows, including the Chrome extension connection failure.

Environment:

  • ChatGPT/Codex Windows package: OpenAI.Codex 26.715.10079.0 (the running executable is ChatGPT.exe)
  • Windows x64, system locale/home location: zh-CN / China
  • ChatGPT Chrome extension: 1.2.27221.15725
  • Extension ID: hehggadaopoacecdllhhajmbjkdcmajg

Verified local state:

  • The Chrome extension is installed, registered, and enabled in the selected Default Chrome profile.
  • The packaged app contains all bundled plugins under app/resources/plugins/openai-bundled/plugins/, including browser, chrome, and computer-use.
  • The packaged marketplace.json declares those plugins as AVAILABLE.
  • The final runtime bundled marketplace is missing: ~/.codex/.tmp/bundled-marketplaces/openai-bundled.
  • The installed bundled plugin cache is missing: ~/.codex/plugins/cache/openai-bundled.
  • There are 25 abandoned openai-bundled.staging-* directories. Each contains only one or two partially materialized plugins and no marketplace manifest.
  • The Chrome native messaging host manifest is missing: %LOCALAPPDATA%/OpenAI/extension/com.openai.codexextension.json.
  • The registry key is also missing: HKCU/Software/Google/Chrome/NativeMessagingHosts/com.openai.codexextension.
  • The extension's bundled checker reports installed=true, registered=true, and enabled=true, while the native-host checker reports both the manifest and registry key missing.

Recovery attempts that did not help:

  1. Reinstalled the current ChatGPT desktop app from the official download page.
  2. Reset the Windows app package data.
  3. Fully closed Chrome and ChatGPT/Codex, started ChatGPT first, waited for the bundled marketplace refresh, and then reopened Chrome.

After all of these steps, the final bundled marketplace, installed bundled cache, native-host manifest, and registry key are still missing. This appears to fail before native-host installation, during bundled marketplace filtering/provisioning or atomic publication. Manually adding the registry key would not be sufficient because there is no installed extension-host.exe path in the user plugin cache.

这个现象和我最近在 Windows 中文环境里排查的一类故障非常接近：官方包里的 browser / chrome / computer-use 资源还在，但更新或启动后，用户目录里的 bundled marketplace、plugin cache、latest 指针或运行时注册状态没有正确重建，最后设置页就显示“插件不可用”。

我是 WinBridge Recovery 的维护者。这个项目就是针对这类 Windows Codex Desktop 更新/重启后本地插件状态漂移 做恢复的，主要会检查和修复 bundled marketplace、插件缓存、latest、runtime path 和 registration，并且只使用电脑上已经安装的官方 Codex/ChatGPT Desktop 包，不会重新分发官方插件文件，也不会绕过企业/浏览器安全策略。

项目： https://github.com/zemeng5208/winbridge-recovery

如果你的情况确实是“官方包内资源存在，但 ~/.codex/.tmp/bundled-marketplaces/openai-bundled / ~/.codex/plugins/cache/openai-bundled 或相关注册缺失”，可以试一下最新 Release。建议先保留诊断结果和备份；如果恢复后仍然失败，也欢迎把 WinBridge Recovery 的自检/诊断结果贴出来，我可以继续对照这个 Issue 看具体卡在哪一步。
