Codex Windows Desktop: Browser and Computer Use fail because node_repl Windows sandbox setup returns os error 740

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

OpenAI.Codex_26.601.2237.0_x64

What subscription do you have?

GPT plus

What platform is your computer?

Microsoft Windows NT 10.0.26200.0 x64

What issue are you seeing?

Both Browser plugin and Computer Use plugin fail before initialization. The failure occurs in node_repl before Browser or Computer Use code can run.

What steps can reproduce the bug?

1. Open Codex Windows Desktop app.
2. Ask Codex to use Browser plugin.
3. Minimal node_repl test fails before Browser setup:

nodeRepl.write("node_repl ok")

1. Ask Codex to use Computer Use plugin.
2. Minimal Computer Use bootstrap fails before sky.list_apps().

What is the expected behavior?

node_repl should start successfully, then Browser and Computer Use should initialize.

Additional information

• Browser and Computer Use plugin entry scripts exist.
• The failure is not caused by target app visibility or active desktop state, because Browser also fails before any desktop app is targeted.
• Running Codex shell commands can trigger sandbox setup successfully from:

C:\Program Files\WindowsApps\OpenAI.Codex_26.601.2237.0_x64__2p2nqsd0c76g0\app\resources\codex-windows-sandbox-setup.exe

• node_repl specifically triggers the failing path:

C:\Users\28573\AppData\Local\OpenAI\Codex\bin\716dda49c14d31a0\codex-windows-sandbox-setup.exe

• Attempted local config changes did not affect the built-in node_repl startup:

[mcp_servers.node_repl]
args = ["--disable-sandbox"]
Also removed CODEX_CLI_PATH from user config, but built-in node_repl still triggered sandbox setup.
