[BUG] Windows desktop app: 'Usage limit reached' persists ~18h while Usage page shows 0% session / 27% weekly / 51% Fable (Max 20x)
Environment
- Claude desktop app on Windows 10 Home (10.0.19045), entrypoint
claude-desktop - Claude Agent SDK 0.3.205
- Plan: Max 20x
- Occurred: evening of July 11 → July 12, 2026 (UTC+8), ~18 hours and counting
Description
Since the evening of July 11 (UTC+8), multiple existing Claude Code sessions in the Windows desktop app are blocked with:
Usage limit reached — You've reached your usage limit. Try again after your limit resets.
Clicking Try again in those sessions immediately returns the same error. This has now persisted ~18 hours — far longer than any 5-hour session window.
At the same time, Settings → Usage shows the account is well under every limit (refreshed July 12, 12:44 PM UTC+8):
- Current session: 0% used
- Weekly, all models: 27% used (resets Sat 9:00 PM)
- Weekly, Fable: 51% used (resets Sat 9:00 PM)
- Usage credits toggle: OFF
Evidence this is stale app/session state, not real quota exhaustion
- New sessions on the same account work at the same time the old sessions stay blocked.
- status.claude.com shows no incidents on July 11–12.
- No proxy/VPN involved (verified: WinHTTP direct, no proxy env vars,
ANTHROPIC_BASE_URL=https://api.anthropic.com). - The affected sessions were running long background workflows (Ultracode multi-agent, 20+ minute runs) when the errors began.

Looks like the same family as #55544 (Windows desktop only), #61673 (desktop shows error while CLI works — state sync), #62125, #61828, #54177, #41084.
Support case
Anthropic support (Fin) case ID: 215475049104289 — Fin recommended filing here for investigation of account-specific state.
Expected behavior
Sessions should unblock when usage is under all limits, or the UI should surface which limit is actually being enforced. Stale "limit reached" state should not persist for ~18 hours across app restarts.
Screenshots of the Usage page and the blocked sessions available on request.
