doom-modeline-segments.el contains these lines:

;; Compatibility
;; @see https://github.com/emacs-mirror/emacs/commit/6e100869012da9244679696634cab6b9cac96303.
(with-eval-after-load 'flymake
  (unless (boundp 'flymake--state)
    (defvaralias 'flymake--state 'flymake--backend-state))
  (unless (fboundp 'flymake--state-diags)
    (defalias 'flymake--state-diags 'flymake--backend-state-diags)))

Maybe updating the package is sufficient.

Best, Arash
