[BUG] Claude Code not responsive at all

What's Wrong?

When I put in anything into Claude Code, it buffers for a really long time. It's not even responding to "hi".

I've tried rolling back to previous working versions before and I'm able to log in. I'm also able to use Claude on the web browser. But I'm not getting any response at all on Claude Code in my VS Code. My VS Code and Claude is completely up to date.

What Should Happen?

It should respond within a few seconds. Especially to just "hi."
