What issue are you seeing?

> codex
internal error; agent loop died unexpectedly
                                            

What steps can reproduce the bug?

After several minutes of debugging, it seems like my $HOME/.codex/sessions has some sessions that were run as root with

> sudo -i
> HOME=/home/<old-user> codex

which causes the session files to be under root ownership.

Using sudo chown -R <old-user> $HOME/.codex/ fixed it.

What is the expected behavior?

A better error message indicating the reason for failure would be nice.
