What's Wrong?

Claude Code crashes every few minutes during normal use. This started after a recent update a few days ago. Prior to the update, Claude Code was working normally.

Also seeing "API Error: Rate limit reached" errors on launch intermittently.

What Should Happen?

Claude Code should remain stable and not crash during a session.
