Why doesn't remove_action() work?

Question

WordPress

Hello! I need to make changes to a product card in a woocommerce plugin. For this I use the remove_action() function. I make changes to the functions.php file of the child theme, but they do not work.

function change_summary() {

remove_action( 'woocommerce_single_product_summary', 'woocommerce_template_single_title', 5 );

}

add_action( 'init', 'change_summary' );

I was looking for solutions on the net, but all the proposed options do not work, while new functions are successfully added to the hooks and work. Tried hooking to different events (including init, wp_loaded, plugins_loaded, woocommerce_single_product_summary with an earlier priority than all other functions), but nothing helps.
