OAuth token revoked · Please run /login

Bug Description
Issue: Persistent "OAuth token revoked" error after Max 20x plan upgrade
Environment:
macOS with bash shell
Claude Code migrated to local installation (~/.claude/local/)
Max 20x plan subscription (upgraded from previous plan)
Problem:
Persistent "OAuth token revoked · Please run /login" error that continues after completing all standard troubleshooting steps.
Steps Already Attempted:
Multiple /logout and clean authentication attempts
Removed auth files: rm -rf ~/.config/claude-code/auth.json
Cleared macOS Keychain: security delete-generic-password -s "claude-code"
Complete config directory removal: rm -rf ~/.config/claude-code/
Terminal restarts and claude update
Migration to local installation with claude migrate-installer
Manual shell alias setup for bash
Verified installation with claude doctor
Current Status:
Claude Code launches successfully after local migration
Authentication prompt appears but OAuth process fails immediately
/bug command non-functional
Error persists despite complete credential reset
Suspected Cause:
Authentication state issue specific to Max 20x plan upgrade, where OAuth handoff between browser authorization and terminal session fails consistently.
