[Bug] Anthropic API Error: coworkKappa feature flag unavailable blocks Claude Code launch

Bug Description
⏺ The config confirms you've used Cowork before — there's a lastSeenRequireCoworkFullVmSandbox key in your Claude app config. The issue is a server-side feature flag: "coworkKappa":{"status":"unavailable"} is being returned from Anthropic's servers right now. This means something changed on the backend for your account — not a local issue. Things to try: 1. Quit and relaunch the Claude desktop app — feature flags are fetched fresh on startup and it may just need to refresh 2. Sign out and back in from the Claude app menu — forces a fresh auth and flag fetch 3. If still broken, contact Anthropic support at https://support.anthropic.com — since it was working before, they can check your account's Cowork entitlement status The "process exited with code 1" is Claude Code failing to launch because Cowork isn't authorized for your session right now. This is not fixable locally.
