solved the problem by chance yesterday.
I have defined a page as the start page. In Customizer I have the choice of displaying the “Front Page Boxes” on “Startseite / from the translation of Homepage”, “Front Page” or “All Pages”.
I always put it on “Homepage”. That was the mistake.
After setting to “Front Page”, the Front Page Boxes work.
