[Bug] Infinite "Verify you are human" loop during login (v1.2.5, Windows portable)

[onionlee21]

Bug description

When using Grok-Desktop on Windows, login gets stuck in a repeated "Verify you are human" challenge loop and never completes.

App version

• Grok-Desktop: v1.2.5 (Portable EXE)

Environment

• OS: Windows (desktop usage)
• Install type: Portable
• Launch command:
  Grok-Desktop_Portable-v1.2.5.exe --user-data-dir="C:\Program Files (x86)\Acus\Grok\Grok1"
• Date observed: April 10, 2026

Steps to reproduce

1. Start Grok-Desktop v1.2.5 (portable).
2. Open login flow (xAI / Google / Apple route through grok.com).
3. Complete the "Verify you are human" check.
4. Wait for redirect.

Actual result

The app returns to another "Verify you are human" prompt (loop), so login cannot finish.

Expected result

After passing verification once, login should proceed to authenticated session.

Notes

• This appears to be a web-auth/challenge handling issue inside the desktop wrapper.
• Same account/login flow works more reliably in a normal browser session (grok.com), so this may be app-side cookie/session/challenge persistence behavior.
• The app uses grok.com and accounts.x.ai web auth flow.

What I already tried

• Re-launch app
• Retry login multiple times
• Use separate user-data profile directories
• Still loops

Request

Could you investigate challenge/cookie/session handling around anti-bot verification flow in the embedded webview window?
