After upgrading Codex Desktop today, two Codex local runtime features are broken.

Environment:

  • Windows
  • Codex Desktop log shows app.version=0.125.0-alpha.3
  • Browser Use plugin: openai-bundled/browser-use/0.1.0-alpha1
  • Workspace: E:\job-picc\ebs-shop-backend\ebs-trade-service

Issue 1: bundled workspace dependencies fail to install
Steps:

  1. Call load_workspace_dependencies()
  2. It returns: No bundled workspace runtime dependencies are configured yet. Call install_workspace_dependencies() to install them.
  3. Call install_workspace_dependencies()
  4. It fails with: Failed to install workspace dependency runtime.

Issue 2: Browser Use in-app browser cannot navigate to external URL
What works:

  • setupAtlasRuntime({ backend: "iab" }) succeeds
  • agent.browser.nameSession(...) succeeds
  • agent.browser.tabs.new() succeeds and creates about:blank

What fails:

  • tab.goto("https://www.bing.com/search?q=bilibili")

Error:
failed to start codex app-server: 系统找不到指定的路径。 (os error 3)

Notes:

  • In-app browser is open, current URL is not navigated/about:blank.
  • System global Node works: C:\Program Files\nodejs\node.exe, v22.22.2.
  • System Python alias was disabled; no global Python is currently resolved.
  • This does not look project-specific. It looks like Codex Desktop app-server / bundled dependency runtime path is broken after upgrade.

What steps can reproduce the bug?

Steps to reproduce:

  1. Start Codex Desktop on Windows.
  2. Open a Codex session with the Browser Use plugin enabled.
  3. Run the workspace dependency check:

load_workspace_dependencies()

Actual result:
No bundled workspace runtime dependencies are configured yet. Call install_workspace_dependencies() to install them.

  1. Run:

install_workspace_dependencies()

Actual result:
Failed to install workspace dependency runtime.

  1. Test Browser Use in the in-app browser with:

const { setupAtlasRuntime } = await import("C:/Users/admin/.codex/plugins/cache/openai-bundled/browser-use/0.1.0-alpha1/scripts/browser-client.mjs");
await setupAtlasRuntime({ globals: globalThis, backend: "iab" });
await agent.browser.nameSession("repro");
globalThis.tab = await agent.browser.tabs.new();
await tab.goto("https://www.bing.com/search?q=bilibili");

Actual result:
failed to start codex app-server: 系统找不到指定的路径。 (os error 3)

Expected result:

  • install_workspace_dependencies() should install/configure the bundled workspace runtime successfully.
  • Browser Use should be able to navigate the in-app browser to an external HTTPS URL.

Environment:

  • OS: Windows
  • Codex Desktop package: OpenAI.Codex_26.422.3464.0_x64__2p2nqsd0c76g0
  • App version from logs: 0.125.0-alpha.3
  • Browser Use plugin: openai-bundled/browser-use/0.1.0-alpha1

Notes:
This started after upgrading Codex Desktop. The Browser Use plugin can initialize and create an about:blank tab, but external navigation fails when Codex tries to start the app-server. This does not appear to be project-specific.

What is the expected behavior?
