[BUG] Invalid API key on MacOS

Environment

• Platform (select one):
• [x] Anthropic API
• Claude CLI version: 0.2.38 (Claude Code)
• Operating System: macOS 15.3
• Terminal: Terminal App

Bug Description

I have logged in to Claude Code successfully, but in terminal, the input area becomes grey and does not allow enter any prompts. (Return does not work).

Subsequent start of Claude also gives this error.
Invalid API key · Please run /login

My account is defined with Developer Role in our organization, but it still reads an api-key somewhere and reject it.

From where does Claude read the api-key?

Steps to Reproduce

Here are the steps to reproduce:

brew uninstall npm
brew uninstall node

rm -Rf ~/.npm-global
rm -Rf ~/.npm
rm -Rf ~/.claude
rm -Rf ~/.claude.json

brew install npm
brew install node

npm install -g npm@11.2.0
npm install -g @anthropic-ai/claude-code

Expected Behavior

Login successfully and execute prompts.

Actual Behavior

Getting Invalid API key · Please run /login
