Suddenly single post is broken

Hello,
I have a problem with the single post page, suddenly today.
am I the only one?
I did not install anything new and yesterday everything worked it all properly.
Today, suddenly, I’ve posted 5 posts and all are broken

some examples:
https://www.immaginidivertentissime.com/banana-su-banana/
https://www.immaginidivertentissime.com/casualita-divertenti/

it looks like I’m redirect to the Archive instead of the single post
Anyway, as you can see I’m missing Title, Categories and Tag

these are normal (correct) post:
https://www.immaginidivertentissime.com/sono-tutti-miei/
https://www.immaginidivertentissime.com/la-stessa-foto-20-anni/

until yesterday, everything worked correctly
and since yesterday I did not manual install nor updated anything

there was an automatic wordpress update last night I saw

I kindly ask you for help

Thanks
Regards
