Wrong number of arguments: #[nil ((vertico-multiform--toggle-mode

(vertico-multiform-vertical 'vertical-reverse-mode)
*** Eval error ***  Wrong number of arguments: #[nil ((vertico-multiform--toggle-mode mode)) ((mode)) nil nil nil], 1

I started getting error just today though I've not touched this code in my init for a long time. I use this line in a function to toggle (C-l) between unobtrusive and reverse-vertical list. I may have copied the idea from somewhere here. I deleted all *.elc files. That didn't help. Here's the function and use-package code block.

Thanks for any help or advice.

(use-package vertico-multiform
  :after (vertico-flat)
  :bind (:map vertico-map
              ("M-q"   . vertico-multiform-flat)
              ("C-l"   . my/vertico-multiform-unobtrusive)
              ("C-M-l" . embark-export))

  :config
  (defun my/vertico-multiform-unobtrusive ()
    "Toggle between vertico-unobtrusive and vertico-reverse."
    (interactive)
    (vertico-multiform-vertical 'vertico-reverse-mode))
  :init (vertico-multiform-mode 1))

  :custom .... a very long section continues

vertico-multiform-vertical has been changed to not accept an argument anymore. You can use vertico-multiform--toggle-mode instead.
