Codex app in-app browser automation fails with "failed to start codex app-server: The system cannot find the path specified. (os error 3)" on Windows

I’m using Codex Desktop on Windows and browser automation is failing in the in-app browser.

What works:

• The Codex in-app browser opens correctly
• I can manually load pages in the in-app browser
• Example page:

https://casinobonusstreak.com/wp-admin/admin.php?page=fluentcrm-admin#/

• Node was updated and the earlier Node version issue appears resolved

What fails:

• As soon as Codex tries to inspect or control the live in-app browser tab, it errors with:

failed to start codex app-server: The system cannot find the path specified. (os error 3)

Important details:

• This is happening inside the Codex in-app browser, not Firefox or another external browser
• The page is already open and visible in the Codex browser pane
• The failure happens when automation attempts to attach to or control the tab

Expected behavior:

• Codex should be able to inspect and control an already open in-app browser tab

Actual behavior:

• Codex throws the app-server path error and cannot automate the page

Steps to reproduce:

1. Open Codex Desktop on Windows
2. Open the in-app browser
3. Navigate to a live page, for example:

https://casinobonusstreak.com/wp-admin/admin.php?page=fluentcrm-admin#/

1. Ask Codex to inspect or control the current in-app browser tab
2. Codex fails with:

failed to start codex app-server: The system cannot find the path specified. (os error 3)

Environment:

• Windows
• Codex Desktop
• In-app browser open on a logged-in WordPress / FluentCRM page
