Comment (by charlestonsw):

 plugins_url() allows the first param to be optionally set to '' (the
 default) which throws this warning for PHP 8.2.3 (probably any PHP 8
 version).

 Plugin or theme developers SHOULD be developing with WP_DEBUG on, which
 then throws this error fairly early in most instances.  In my case trigger
 a stack of "headers already sent" messages.

 IMO WordPress Core function defaults should not lead to PHP warnings for
 supported/recommended versions of PHP.   At the very least the
 plugins_url() should be added to the exceptions list here for PHP 8.0/8.1
 etc.:
