Array offset null

It appears with the recent update to WordPress core 6.1 (running PHP8.1) there seems to be a few error/warning notifications around validating for null offsets. I’ve identified these issues down to 3 specific files, and the same if statement within them, I would suggest adding a null validation prior to the check to resolve the issues. Here are the files and the lines I would add the validations before.

limit_offset.php – line 44

//Suggest adding initial variable validation
if ( $wp_nav_plus_limit_offset_options === null ){
	return $items;
}

menu_segment.php – line 43

//Suggest adding initial variable validation
if ( $wp_nav_plus_menu_segment_options === null ){
	return $items;
}

start_depth.php – line 54

//Suggest adding initial variable validation
if ( $wp_nav_plus_start_depth_options === null ){
	return $items;
}
