Where did the choice of page template in wordpress go?

Question

WordPress

Some kind of anomaly in Wordpress, the template selection was gone. At the same time, it is available in the local version of the site.

Answer 1

It's just that when there are no template files, there is no template selection. It is worth creating at least one template in the theme folder and everything will appear.

Answer 2

Switch the topic to another one, then change it back.

Answer 3

Same story. But for me, due to the fact that I deleted the file with styles in the child theme, because it was not used for styles. And, as you know, it is mandatory.
