[BUG] Claude Cowork #33120

Preflight Checklist

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

What's Wrong?

Cowork displays 'API Error: Rate limit reached' immediately on every action. Chat mode and Claude Code CLI work perfectly on the same account. Usage is well under quota. This matches the account-level bug reported in #33120 (now locked).

Environment:

• Claude Desktop v1.1.7714
• Windows 11 Pro 25H2 (Build 26200.8037)
• Pro plan

Symptoms:

• Cowork shows 'API Error: Rate limit reached' on every action
• Chat mode works perfectly on the same account
• Usage is well under quota
• Issue is account-specific and persists across all restarts

What I've tried:

• Sign out / sign back in — no change
• Enabled Hyper-V (was disabled — this fixed a prior IsGuestConnected timeout)
• Submitted support ticket — Fin claimed to process a reset (Conv ID: 215473576935003)
• Escalation email sent March 21 — no human response after 2 days
• Rate limit error persists through all of the above

Impact:
Active project completely blocked. Cowork is non-functional on a paid Pro plan with no ETA on resolution from support.

Requesting server-side account-level rate limit reset. Happy to provide logs or additional diagnostics.

What Should Happen?

Cowork should connect and process tasks normally, as Chat mode does on the same account.

Hyper-V was disabled — enabling it fixed IsGuestConnected timeout
but Rate limit error persists. Account-level bug, not actual usage limit.
