is_home() doesn't work on Blog Posts Page

Hello,

i'm trying to get the metadata for the blog posts page from the .entry-header and insert it before the content. The change should only be made on the blog overview page, but not on the individual page.

I have selected a static page for the blog posts in the Wordpress read options. Unfortunately the if condition "is_home();" does not work.

I use GeneratePress 2.4.2 and Pro 1.10.0 with a child theme.
I have already deactivated all other plugins.
Without the query is_home() it works, but then also for single posts.

What could be the problem?

if ( is_home() ){
		add_action( 'after_setup_theme', function() {
			remove_action( 'generate_after_entry_title', 'generate_post_meta' );
			add_action( 'generate_after_entry_header', 'generate_post_meta' );
		} );
	};
