website got broke

[tolook_design]

Hi, need help, our website www.tolook.net is no longer visible!
There is this instead:
Scopri di pi\u00f9 riguardo la risoluzione dei problemi in WordPress.</a></p>","data":{"status":500,"error":{"type":1,"message":"Uncaught Error: Failed opening required '/web/htdocs/www.tolook.net/home/wp-content/themes/lay/utility.php' (include_path='.:/php8.3/lib/php') in /web/htdocs/www.tolook.net/home/wp-content/themes/lay/functions.php:7\nStack trace:\n#0 /web/htdocs/www.tolook.net/home/wp-settings.php(672): include()\n#1 /web/htdocs/www.tolook.net/home/wp-config.php(93): require_once('...')\n#2 /web/htdocs/www.tolook.net/home/wp-load.php(50): require_once('...')\n#3 /web/htdocs/www.tolook.net/home/wp-blog-header.php(13): require_once('...')\n#4 /web/htdocs/www.tolook.net/home/index.php(17): require('...')\n#5 {main}\n thrown","file":"/web/htdocs/www.tolook.net/home/wp-content/themes/lay/functions.php","line":7}},"additional_errors":[]}

We got some e-mails from Wordpress on the admin mail saying:
