PHP 8 compatability issue

Warning: Undefined array key "status" in webform_submission_send_mail() (line 249 of /var/www/clients/client1/web1/web/modules/webform/includes/webform.submissions.inc).

Perhaps line 249 could be:
if (!$send_disabled && isset($email['status']) && !$email['status']) {

I can't recreate this. If I disable an email listed on node/*/webform/emails then $email['status'] equals zero. And if I remove the email address altogether then it doesn't call webform_submission_send_mail().

Can you provide some steps to recreate on a fresh site?

I'm on a PHP 8.1 (fpm, web server is Apache, MariaDB 10.6) installation on Linux and I received a TypeError in webform.admin.inc (the path is /admin/config/content/webform):

Another error in /admin/content/webform:
