Sorry to jump back in on this one, but I have been getting it pretty persistently since late last year.

My debug output looks almost identical to @SoCuul:

HANGS HERE

The above command to list out the number of paths hangs for me as well.

Back to your first set of questions in this issue:

  1. Yes, near as I can tell, this is happening every time
  2. The bare, non-eval command hangs as does the non-eval with the --no-rehash option
  3. I moved .zshrc and .zprofile to .bak and the following completes without hanging:
adavis@AndyDavisMacBookPro-3 ~ % /opt/homebrew/Cellar/rbenv/1.3.0/libexec/rbenv
init - zsh
export PATH="/opt/homebrew/Cellar/rbenv/1.3.0/bin:${PATH}"
export PATH="/Users/adavis/.rbenv/shims:${PATH}"
export RBENV_SHELL=zsh
command rbenv rehash 2>/dev/null
rbenv() {
  local command
  command="${1:-}"
  if [ "$#" -gt 0 ]; then
    shift
  fi

  case "$command" in
  rehash|shell)
    eval "$(rbenv "sh-$command" "$@")";;
  *)
    command rbenv "$command" "$@";;
  esac
}
adavis@AndyDavisMacBookPro-3 ~ %

I'll try digging in and see if there's something specific causing issues. I was running OMZ, but I thought I had that disabled and was still hanging.
