The front-page.php is a File inside your Child Theme. In the link I posted above, they added an update to this file which fixed the same issue you’re having. So all you would need to do is replace the front-page.php file with the newer version (1.1).
Did you make any changes or customizations to this file directly? If you didn’t, then you can swap it out with the new file and see the changes show up instantly.
