What's Wrong?

Here you go — copy this whole thing:

Title: Windows Max subscription - OAuth login shows "Upgrade" button, no login option
Body:
Environment:

Windows
Claude Code version 2.1.19
Active Max subscription
No ANTHROPIC_API_KEY environment variable set

Problem:
When selecting "Claude account with subscription" during login, the browser opens to a page that only shows "Upgrade to Max or Pro" button. There is no login or sign-in option anywhere on the page. Cannot authenticate despite having an active Max subscription.
Steps tried (none worked):

/logout
claude update
Restart terminal
Clear browser cache and cookies for claude.ai
Tried incognito/private browser window
Verified no other Claude accounts signed in
Verified same email as Max subscription
Contacted support — received only automated responses repeating the same steps

Notes:
Support acknowledged this matches the January 22nd authentication incident that was marked as "resolved" — but the problem clearly persists.
I am paying $140/month for Max and cannot use Claude Code because the OAuth flow is broken. In 1969 we put men on the moon with less computing power than a cell phone. In 2026, Anthropic cannot make a login page work on Windows.
Please fix this.

What Should Happen?

Expected behavior:
When selecting "Claude account with subscription" and the browser opens, I should see a login/sign-in option where I can enter my email and authenticate with my existing Max subscription. After authentication, Claude Code should recognize my Max plan and allow me to use the tool.

Error Messages/Logs

Steps to Reproduce

Steps to reproduce:

Have an active Claude Max subscription
Install Claude Code on Windows via npm install -g @anthropic-ai/claude-code
Open terminal (PowerShell or CMD)
Run claude
Select theme (Dark mode)
Select "1. Claude account with subscription - Pro, Max, Team, or Enterprise"
Browser opens to a page showing only "Upgrade to Max or Pro" button
No login option exists on this page
Cannot proceed with authentication

No code or files involved — this is a fresh install attempting first-time authentication.

Model:
N/A — cannot run /model because authentication fails before reaching the Claude Code interface. The login flow breaks before any model can be selected.

Claude Model

None
