What's Wrong?

I had Claude Code created me network monitoring node using Python, and after that Claude Code crashed with error on the side says "High memory usage (50.4GB) ".
The monitoring node isn't running automatically, but every time I open a Claude Code session a high memory usage indicator shows up and memory usage keeps growing.
The issue only happened on my main PC, I don't see such issue on my second computer
