Personally, I got tired of weird quirks like this with vterm and now bind this command to the key I used to have vterm on to spawn my actual terminal (st) in my current directory. It's probably not what most people want from vterm, but I prefer it.

  (defun open-term-here ()
    "open st in `default-directory`"
    (interactive)
    (call-process-shell-command
     (concat "st bash -c \"cd "
      default-directory
      " && exec zsh\"")
     nil 0))

I also do this, C-x t to open a tmux tab to whatever directory the current buffer is:

  (defun tmux-here ()
    (interactive)
    (if (not (eq (getenv "TMUX") ""))
        (shell-command (format "tmux new-window -c %s" default-directory))
      (error "Not inside a tmux session.")))

I know, I know, tmux is slow and should never be used. I like it, OK.
