Account recovery request

[Arnie97]

Hello #! administrators, I'm the owner of the [email protected] account.
Due to some .zshrc misconfiguration, I locked myself out of the zsh login shell :(
My SSH credentials are not lost, but I could only see the SSH banner now, just like if /sbin/nologin is used.

Could you please helping me recover my #! access, by either

1. Removing the dotfile /home/arnie97/.zshenv, or
2. Changing my login shell to /bin/sh (Debian Almquist Shell) in /etc/passwd

Thank you!
