What's Wrong?

The Claude iOS app crashes instantly when attempting to open an active remote Claude Code session. The crash is 100% reproducible and persistent across multiple relaunch attempts. Force-closing and relaunching the app results in the same instant crash every time.

What Should Happen?

The app should open and connect to the active remote Claude Code session as normal.
