What's Wrong?

When Claude in Chrome is enabled on WSL2, Claude Code crashes on startup with an unhandled error. The error prevents the app from starting, making it impossible to disable the feature via /chrome command.

What Should Happen?

• Claude Code should detect unsupported platform BEFORE allowing user to enable
• Or gracefully disable the feature on unsupported platforms at startup
• Should NOT crash and lock user out

Error Messages/Logs

636 | Never reuse tab IDs from a
previous/other session. Follow these
guidelines:
2637 | 1. Only reuse an existing tab if the
user explicitly asks to work with it
2638 | 2. Otherwise, create a new tab with
mcp__claude-in-chrome__tabs_create_mcp
2639 | 3. If a tool returns an error
indicating the tab doesn't exist or is
invalid, call tabs_context_mcp to get fresh
tab IDs
2640 | 4. When a tab is closed by the user or
a navigation error occurs, call
tabs_context_mcp to see what tabs are
available

Workaround

Had to use an existing open session to run /chrome and disable. Without that, would have needed factory reset.
