Could I ask that your team move this up in priority? For us developers who work locally with XDebug, WP_DEBUG, and logging enabled, it completely breaks the WP Admin UI and floods the logs. This issue has been known about since July, the fix is extremely easy and only occurs in 2 places:
/var/www/html/public/content/plugins/gravityforms/includes/fields/class-gf-field-list.php on line 167
/var/www/html/public/content/plugins/gravityforms/includes/fields/class-gf-field-repeater.php on line 584
PHP 8.3 is coming out soon and WordPresss works just fine with PHP 8.2 (which was mentioned as a reason last time why this hasn’t been fixed yet).
