What's Wrong?

Environment

• Claude Desktop app: 1.24012.9 (Windows)
• Bundled Claude Code: 2.1.219
• OS: Windows 10 Pro (19045), x64

What happened
In a desktop Code session, using the /remote-control command:

1. Typed /remote-control → connected
2. Typed /remote-control → to disconnect
3. Typed /remote-control → to reconnect

From step 2 onward, every /remote-control returns:
"Remote Control failed to disconnect: Cannot read properties of
undefined (reading 'session_url')"
The session then gets stuck: every subsequent /remote-control repeats
the same error and never recovers. The disconnect appears to crash on an
undefined session_url, so the connected/disconnected state never flips.
This occurred BEFORE enabling "Enable remote control by default," and
toggling that setting ON or OFF made no difference.
Workaround
Fully quitting and reopening the desktop app clears the stuck state.
Typing /remote-control again does NOT recover it.
Expected
/remote-control disconnect should handle a missing session_url gracefully
instead of throwing, and the session shouldn't get wedged.

What Should Happen?

Typing /remote-control many times should work nicely connected- disconnect - connected ... , without any issue.
