 In our case, our website (latest WP release) was throwing fatal errors
 when trying to switch to PHP 8.1. After much digging, we found the issue
 to be in the wp-includes/class-wp-widget-factory.php file, line 62. The
 line was formerly:

 {{{#!php
 <?php
 $this->widgets[ $widget ] = new $widget();
 }}}

 And to fix the site, we modified the line to be as follows:

 {{{#!php
 <?php
 $this->widgets[ $widget ] = new $widget( $widget, $widget );
 }}}

 This completely resolved the issue in our case. Please update the core
 file to reflect this change in the move toward PHP 8+ compatibility.
 Thanks.
