What's Wrong?

Starting yesterday morning, I can no longer use /remote-control in my main claude code instance. I use it from the windows app. I've changed nothing, and I'm pretty sure Claude code updated and it stopped working at that point. I can start a new instance, and remote control will work in that one, so it's just my main one that's broken for some reason...

I've restarted the app multiple times (ensuring it's all actually closed in task manager), restarted the computer, etc. with no changes.

Using claude to try and diagnose its-self, here's some of what it's said:

Claude Code (CLI): 2.1.255 (build 2.1.255.2a3) — entrypoint claude-desktop
Claude Desktop app: 1.40609.1 (Windows Store build)
Model: claude-opus-4-8

What Should Happen?

I should be able to use remote control like I've been doing for months.
