New description:

 In WordPress core 6.0, plugins and themes that register widgets cause a
 fatal error for sites running on PHP 8.0. Here is an example:
 {{{
 Uncaught ArgumentCountError: Too few arguments to function
 WP_Widget::__construct(), 0 passed
 }}}
 A solution that is working for me is to edit line 61 of wp-includes/class-
 wp-widget-factory.php so that
 {{{
 new $widget()
 }}}
 gets 2 empty strings passed to it, e.g.

 {{{
 new $widget('', '')
 }}}
