Starting with Emacs 29, ‘define-key’ is deprecated in favor
of the new function ‘keymap-set’.  So your definition would
(slightly) simplify to:

  (keymap-set comint-mode-map "C-x <up>" #'windmove-up)

See, C-h f keymap-set, 
     M-: (shortdoc 'keymaps), and
     M-: (info "(emacs) Init Rebinding")
