What's Wrong?

I am re-installing claude code. I have been using it without issues until today. I got an error after running claude --resume. I was instructed in installing claude code and installing latest version. Since then I can't install claude code. Claude desktop is working without issues. when I try to install , the installation hangs.

What Should Happen?

I expect no issues in re-installing claude code.
