What's Wrong?

Claude Code silently crashes immediately after the TUI appears when running from the user's home directory (~) with config-based OAuth authentication. The process exits with no error message.

What Should Happen?

Claude Code TUI is functional.

Steps to Reproduce

1. Authenticate via claude (creates oauthAccount in ~/.claude.json)
2. Ensure CLAUDE_CODE_OAUTH_TOKEN is not set: unset CLAUDE_CODE_OAUTH_TOKEN
3. Run from home directory: cd ~ && claude
4. Accept trust dialog if prompted
5. TUI appears briefly, then exits silently

Additional Information

• OS: RHEL 8.7 (kernel 4.18.0-425.19.2.el8_7.x86_64)
• Shell: bash

I've found that setting CLAUDE_CODE_OAUTH_TOKEN env var is a workaround:
CLAUDE_CODE_OAUTH_TOKEN=<your-token> claude

Other cases that work fine:

• ✅ Any other directory with config-based OAuth (cd /tmp/test && claude)
• ✅ Home directory with env-based OAuth (CLAUDE_CODE_OAUTH_TOKEN=... claude)

What crashes:

• ❌ Home directory + config-based OAuth only
