Remote Control no longer available — was previously working

Description

/remote-control is no longer available. It was previously working on this account and has stopped without any communication or changelog notice.

Steps to reproduce

1. Inside a Claude Code session, type /remote-control → returns "Unknown skill: remote-control" (command doesn't appear in the skill list at all)
2. From the terminal, run claude remote-control → returns:

Error: Remote Control is not yet enabled for your account.
Assertion failed: !(handle->flags & UV_HANDLE_CLOSING), file src\win\async.c, line 76

Expected behaviour

Remote Control should work as it did previously. This account has been using Remote Control regularly — this is not a first-time setup issue.

Environment

• Claude Code version: 2.1.85
• Platform: Windows 11 Pro (10.0.26200)
• Shell: bash
• Plan: Individual (Pro) — same plan as when Remote Control was working
• Auth: claude.ai OAuth (not API key)

Additional context

• No changes were made to authentication, plan, or settings between the last successful use and this failure.
• The UV_HANDLE_CLOSING assertion failure in the error output suggests a possible Windows-specific regression in addition to the feature flag issue.
