I suspect the problem is that "prompt" calls "add-zsh-hook -D ..." which
is muddling with the hooks arrays while they're still being walked by
the hook-processing internals.

As a workaround, try setting the prompt theme from the zle-line-init
widget; for ex:

zle-line-init() { prompt wunjo; zle reset-prompt; zle -R }
zle -N zle-line-init

Refine by creating the widget in chpwd hooks and deleting it from within
itself after the zle -R.
