Resume crashes with 'Cannot read properties of null (reading split)'

Bug Description

Every time I click "resume" to open a recent conversation, Claude Code crashes with the following error:

Cannot read properties of null (reading 'split')

This happens consistently across all conversations, not just a specific one.
