Well, the problem is indeed that you have PHP 5.6 instead of 7.4.
Please remember that a web server may have multiple PHP versions installed on it but only one of them will be active at any one time. Also remember that the PHP version reported by your hosting control panel is the version of PHP the hosting control panel itself runs under, not necessarily the same version of PHP your site runs under.
While most modern hosts allow you to set up the default PHP version at the hosting account level, most older hosting control panels (and many custom control panels created by the hosts themselves) change the PHP version by modifying the .htaccess file. When you have a blank site there is no .htaccess file therefore the server falls back to its default PHP version, usually an older one. In your case, PHP 5.6.
Go to your hosting control panel and select PHP 7.4 as the default PHP version. If there is no such option or, at least, you cannot find one please contact your host so they can guide you. Then you can rerun Kickstart. Kickstart will “see” the special line in the .htaccess file and carry it forward through the restoration so that Kickstart and the site restoration script (ANGIE) run under PHP 7.4.
