Browser pane tool fails on all read/screenshot calls with "Policy check temporarily unavailable"

What's Wrong?

The in-app "side browser" pane (Claude Browser tool) opens and connects fine — tab-context checks succeed — but every call that reads or views page content (screenshot, get_page_text, read_page, find) fails immediately with:

"Policy check temporarily unavailable; retry."

This has persisted for ~24 hours across multiple sessions. A full restart of the Claude Code desktop app did not resolve it (the app restart did clear a separate symptom where the pane was stuck showing a stale page, but the underlying read/screenshot error remains identical after restart).

Platform: Windows 11 Pro
Claude Code: desktop app

What Should Happen?

The browser tool should be able to take a screenshot or read the page content instead of failing immediately.

Steps to Reproduce

1. Open the Claude Browser pane / navigate to any page
