I'm still unable to reproduce. I've installed the needed packages from
GNU ELPA (I believe), and then I've applied

# src/emacs -Q -l tramp \
  -l ~/.emacs.d/elpa/helm-20230129.1448/helm-autoloads.el \
  -l ~/.emacs.d/elpa/helm-core-20230117.1925/helm-core-autoloads.el \
  -l ~/.emacs.d/elpa/async-20221228.1315/async-autoloads.el

M-x helm-find-files
=> custom-initialize-reset: In ‘Find Files’ source: ‘helm-find-files-get-candidates’ 
   (user-error "Error: file-notify-error (\"File watching is not available\" \"Too many open files\")")

M-x helm-find-files
/home/albinus/ RET
=> Proper dired listing.

Grrrr. Do you like to run a jitsi session together with me, for debugging?

Best regards, Michael.
