Windows Desktop: openai-bundled marketplace cache rebuilds incompletely, hiding Browser and Computer Use plugins

Summary

On Windows Codex Desktop, the temporary openai-bundled marketplace cache can rebuild incompletely and expose only the chrome plugin. When this happens, browser@openai-bundled and computer-use@openai-bundled are still enabled and present in the real plugin cache, but disappear from the plugin page / tool availability because the marketplace source only indexes chrome.

This has happened repeatedly on the same Windows machine, at least twice in two days: June 13, 2026 and June 15, 2026.

Environment

• OS: Windows
• Codex App package version: 26.609.4994.0
• openai-bundled marketplace source from config: %USERPROFILE%\.codex\.tmp\bundled-marketplaces\openai-bundled
• Enabled plugins in config:
• computer-use@openai-bundled
• chrome@openai-bundled
• browser@openai-bundled
• Real cache currently contains:
• %USERPROFILE%\.codex\plugins\cache\openai-bundled\browser\26.609.41114
• %USERPROFILE%\.codex\plugins\cache\openai-bundled\chrome\26.608.12217
• %USERPROFILE%\.codex\plugins\cache\openai-bundled\computer-use\26.609.41114

Observed state during failure

%USERPROFILE%\.codex\.tmp\bundled-marketplaces\openai-bundled\plugins contains only:

chrome

Meanwhile %USERPROFILE%\.codex\plugins\cache\openai-bundled contains:

browser
chrome
computer-use

computer-use@openai-bundled, chrome@openai-bundled, and browser@openai-bundled remain enabled = true in config.toml.

Expected behavior

If the real bundled plugin cache contains browser, chrome, and computer-use, and all three are enabled, the temporary marketplace cache should expose all three plugins after rebuild.

Actual behavior

The temporary marketplace cache exposes only chrome. Browser and Computer Use disappear from the plugin page / available tools even though their real cache directories still exist and the plugins are enabled.

Workaround that restores visibility

1. Stop any residual extension-host.exe helper if it is holding files under openai-bundled\plugins\chrome\extension-host\windows\x64.
2. Rename, rather than delete, %USERPROFILE%\.codex\.tmp\bundled-marketplaces\openai-bundled to a timestamped backup.
3. Fully restart Codex Desktop so it regenerates the temporary openai-bundled marketplace.
4. Reopen or refresh plugin visibility.

This workaround restored visibility previously, but the failure recurred.

Additional note

This appears separate from the Computer Use startup/runtime error involving Package subpath './dist/.../computer_use_client_base.js' is not defined by "exports". The issue here is plugin visibility / marketplace indexing before any Computer Use startup attempt.
