What's Wrong?

I'm a Claude Pro user and using Claude Code via Claude Code for VS Code plugin.
I tried it on both VS Code and Cursor; after logging in to Claude Code, I was immediately and repeatedly asked to run /login.
I tested it on both Ubuntu 22.04 and Windows 11.
I also checked the .credentials.json, the subscriptionType property seems weird.

{"claudeAiOauth":{"accessToken":"sk-ant-oat01-","refreshToken":"sk-ant-ort01-","expiresAt":1759435078288,"scopes":["user:inference","user:profile"],
"subscriptionType":null}}

What Should Happen?

As a Pro user, I should be able to interact with Claude Code without seeing the error message below.
