What's Wrong?

The .claude.json get filled by junk and become bigger and bigger and when it's too big it makes my whole computer freeze, lag, and unresponsive when using CC.

Renaming .claude.json to .claude.json.old to make him disappear, launching CC to create a new .claude.json automatically, now it's running fine (and the .claude.json is 32KB for now) I think he is filled by the history and idk why it makes CC and my computer running slow and lag.

What Should Happen?

The computer should run smooth and the .claude.json shouldn't become that big (it shouldn't retain the whole history)
