It is also not very clear for me what could be broken in your setup.
One guess would be that I use non-standard :desk link property to setup
default link description. That property actually need some extra custom
code to work. I imagine that it might somehow interfere with the
existing org code when set.
Can you try the following simplified code?

(defun org-id-prompt-id ()
  "Prompt for the id during completion of id: link."
  (let ((org-refile-history nil)
        (org-refile-cache nil)
        (org-refile-target-verify-function nil))
    (let ((prompt-ans (org-refile-get-location "Select org entry")))
      (prog1
          (or (org-id-get (seq-find #'markerp
                                    prompt-ans)
                          'create)
              (user-error "Cannot find ID of the entry: %s" prompt-ans))
        (setq org-id-history org-refile-history)
        (setq org-id-cache org-refile-cache)))))

(defun org-id-link-complete (&optional arg)
  "Completion function for id: link."
  (let* ((id (org-id-prompt-id)))
    (format "id:%s" id)))

(org-link-set-parameters "id"
                         :complete #'org-id-link-complete)

P.S. You can use %^t instead of %(org-insert-time-stamp ...).
