Environment

• OS: Windows 11 Enterprise 10.0.26100

• Claude Code installed via: npm (global)
• Install path: C:\Users\iwheeler\AppData\Roaming\npm\node_modules\@anthropic-ai\claude-code

Description

This error occurred during a normal Claude Code session. The stack trace points to insertChild calls in the CLI's rendering layer (likely Ink/React terminal UI), suggesting a rendering issue where a Node instance from one context is being passed to another context that doesn't recognize it.

The error is not actionable from the user side — it appears to be an internal rendering bug.

Steps to Reproduce

The error occurred during a standard interactive session. No specific reproduction steps identified — it appeared spontaneously.
