What's Wrong?

Hi, I am using Claude Code via PyCharm's integration. While works most of the time, for some projects, it keeps getting "Invalid API key · Please run /login", despite I am on a MAX subscription. With the same device, and the same claude account, it works for other projects. Why it is the case?

What Should Happen?

Claude should work.
