[BUG] Pro subscription not recognized - "There's an issue with the selected model" for all models on Windows

Preflight Checklist

• I have searched existing issues and this hasn't been reported yet
• This is a single bug report (please file separate reports for different bugs)
• I am using the latest version of Claude Code

What's Wrong?

Claude Code does not work with any model when authenticated with a Claude Pro subscription.
Every model (Sonnet 4.6, Opus 4.7, Haiku) returns the same error.
The web interface at claude.ai works perfectly fine with the same account.

What Should Happen?

Claude Code should recognize the active Claude Pro subscription and allow
using the included models without errors.

Error Messages/Logs

There's an issue with the selected model (claude-sonnet-4-6).

Additional Information

Account email: ander.jbc115@gmail.com
Plan: Claude Pro ($20/month)
The dashboard shows "API Usage Billing" instead of recognizing the Pro subscription.
Re-authentication and full config deletion did not resolve the issue.
My Claude Pro subscription started yesterday (April 22, 2026) and
Claude Code has never worked even once. This is my first day trying
to use it and it's already broken. Very disappointing experience for
a brand new paying customer.

Additional info: I checked my credentials.json file and it shows
"subscriptionType": "pro" and "rateLimitTier": "default_claude_ai",
confirming my Pro subscription IS recognized locally. However the UI
still shows "API Usage Billing" and all models fail.

This worked fine on my other laptop on April 21-22. I am now on a
different laptop and it has never worked here. The environment variable
ANTHROPIC_MODEL was set to "claude-sonnet-4-5-20251001" on this machine
which I removed, but the issue persists.

This appears to be a backend issue where the subscription type is not
being properly validated when selecting models.
