Authentication Failure: OAuth Not Supported for Claude CLI

Bug Description
I have tried many times to authenticate, uninstalling claude and reinstalling.
I first had it setup with google vertex but have since switched to the subscription method but I keep getting this same

API Error: 401 {"type":"error","error":{"type":"authentication_error","message":"OAuth authentication is currently not supported."}}

I have even removed the claude files with rm -rf ~/.claude rm ~/.claude.json and from the npm cache.
I also ran security delete-generic-password -a $USER -s "Claude Code-credentials" and it removed my credentials. I am at a loss
