After tryed to upgrade i got this error. Site is totaly down

Have PHP 8.1

 

We were unable to start a PHP session. You will need to contact your host to adjust your PHP configuration before you can continue. The error reported was: Return type of IPS\_DateTime::format($format, $memberOrLanguage = null) should either be compatible with DateTime::format(string $format): string, or the #[\ReturnTypeWillChange] attribute should be used to temporarily suppress the notice
