The value should be a symbol, not a string:

(setq org-startup-folded 'overview)

customise interface even tries to warn you that something is wrong:

If you select the value from customise interface, Emacs would set it
correctly.  Direct setting is indeed possible, but you need to consult
how the variable is defined.  Note the :type specifier below (also, see
15.4 Customization Types section of Elisp manual).

(defcustom org-startup-folded 'showeverything
  "Non-nil means entering Org mode will switch to OVERVIEW.

This can also be configured on a per-file basis by adding one of
the following lines anywhere in the buffer:

   #+STARTUP: fold              (or `overview', this is equivalent)
   #+STARTUP: nofold            (or `showall', this is equivalent)
   #+STARTUP: content
   #+STARTUP: show<n>levels (<n> = 2..5)
   #+STARTUP: showeverything

Set `org-agenda-inhibit-startup' to a non-nil value if you want
to ignore this option when Org opens agenda files for the first
time."
  :group 'org-startup
  :package-version '(Org . "9.4")
  :type '(choice
	  (const :tag "nofold: show all" nil)
	  (const :tag "fold: overview" t)
	  (const :tag "fold: show two levels" show2levels)
	  (const :tag "fold: show three levels" show3levels)
	  (const :tag "fold: show four levels" show4evels)
	  (const :tag "fold: show five levels" show5levels)
	  (const :tag "content: all headlines" content)
	  (const :tag "show everything, even drawers" showeverything)))

Best,
