Computer Use cannot control Microsoft Edge because URL detection fails despite readable address bar URL

What issue are you seeing?
Codex Computer Use can discover Microsoft Edge windows, but when attempting to capture/control an Edge window, it stops with:
Computer Use has been stopped for this turn because it could not determine the current browser URL on Windows with enough confidence to enforce policy.
This happens even when Edge is showing a normal HTTPS page such as https://example.com/.
I verified that Windows UI Automation can read the Edge address bar URL successfully, but Computer Use still refuses to proceed.
What steps can reproduce the bug?
Feedback ID: no-active-thread-019f3643-dc6c-7662-b7a3-34514c9fb7e2
What is the expected behavior?
Computer Use should detect that the current Microsoft Edge URL is a normal HTTPS URL and allow safe screenshot/control of the Edge window.
Additional information
Environment:
- Microsoft Edge path:
C:\Program Files (x86)\Microsoft\Edge\Application\msedge.exe - Microsoft Edge version observed:
150.0.4078.48 - Display scaling: 150%
- System proxy:
127.0.0.1:7897, withlocalhostand127.*bypassed
I ran a diagnostic script that launched Edge with:
--new-window --force-renderer-accessibility --no-first-run --no-default-browser-check https://example.com/
Windows UI Automation successfully read:
URL: https://example.comElement: 地址和搜索栏
It also read an existing Edge window URL:
https://agentseller.temu.com/newon/product-select
So the URL is readable at the Windows UI Automation layer, but Computer Use's browser URL policy still fails.

I reproduced this on a substantially newer Computer Use build.

``Join the library and 1 more page - Work - Microsoft Edge
sky.get_window_state({ include_screenshot: false, include_text: true })failed with the same URL-verification message.No screenshot, accessibility text, click or text input occurred. The read-only action passed the normal approval review; Computer Use itself returned the failure.
The wording says the URL could not be verified, rather than saying the URL was disallowed. This appears to be an Edge active-tab URL extraction or window-to-address-bar association failure in the native URL-policy path.
Expected: Computer Use should detect the active Edge URL and return the window state. If detection fails, it should report which URL candidates were found and why none was accepted, rather than terminating the whole turn with an unrecoverable generic error.

Update: this now reproduces in Google Chrome as well, using Computer Use plugin 26.721.41059. On an authenticated Vanta page, Computer Use stopped before any interaction because it could not verify whether the current browser URL was allowed. This no longer appears to be Edge-specific.
Reproduced on a newer build, with additional evidence that the Edge native-messaging chain can be live while URL verification still fails.
