Remove action not working on latest version 6.1

Hi,

I used remove_action to modify few things on woocommerce page, product archive page and it’s working fine with older version after the update in latest version remove_action not working anymore. I tried all methods as I know but not get succeed so please guide me if anything changes on latest version.

remove_action( 'woocommerce_before_shop_loop_item_title', 'woocommerce_template_loop_product_thumbnail', 10 );

also tried with init hooks like:

add_action( 'init', 'prefix_remove_action' );
function prefix_remove_action() {
 remove_action( 'woocommerce_before_shop_loop_item', 'woocommerce_template_loop_product_link_open', 10 );
    remove_action( 'woocommerce_before_shop_loop_item_title', 'woocommerce_show_product_loop_sale_flash', 10 );
    remove_action( 'woocommerce_before_shop_loop_item_title', 'woocommerce_template_loop_product_thumbnail', 10 );
    remove_action( 'woocommerce_shop_loop_item_title', 'woocommerce_template_loop_product_title', 10 );
    remove_action( 'woocommerce_after_shop_loop_item_title', 'woocommerce_template_loop_rating', 5 );
    remove_action( 'woocommerce_after_shop_loop_item', 'woocommerce_template_loop_add_to_cart', 10 );

}
`

not any hooks are working.

Thanks in advance for help.
