Desktop app (Windows) crashes when logging into Cloudflare dashboard in the internal browser pane

Environment

• App: Claude Code desktop app, version 2.1.202
• OS: Windows 11 Home 10.0.26200
• Component: internal browser pane (Browser preview)

What happened

Opening the Cloudflare dashboard login (https://dash.cloudflare.com) in the app's internal browser pane and attempting to sign in crashed the entire desktop app — not just the browser pane. This happened repeatedly (several attempts, same result), and after the crashes the app would not launch again until the machine was rebooted.

Suspected trigger: Cloudflare's login page runs bot-protection / Turnstile challenge scripts, which the embedded browser may not handle.

Steps to reproduce

1. In an active session on the Windows desktop app, open the internal browser pane
2. Navigate to https://dash.cloudflare.com
3. Attempt to log in (the page loads its Turnstile/bot-protection challenge)
4. App crashes; relaunch fails until reboot

Expected

Either the page works in the pane, or the pane fails gracefully (blocked page/error) without taking down the app — and a crashed app should relaunch without requiring a reboot.

Impact

• Full app crash + reboot required (session interrupted mid-task)
• No data loss in our case (state was in external services / saved memory), but the recovery path is heavy

Workaround

Using the real Chrome browser (with the Claude in Chrome extension) for bot-protected logins works fine.
