Following the last updates, my current solution:

		if( $product_id &&
		get_post_meta( $product_id, '_catalog', true) == 'yes' &&
		get_post_meta( $product_id, 'disable_price', true) == 'yes' ) {
			if(has_action('woocommerce_after_shop_loop_item_title', 'woocommerce_template_loop_price') ) {
				remove_action( 'woocommerce_after_shop_loop_item_title', 'woocommerce_template_loop_price', 10 );
				$WCFM->wcfm_has_catalog = true;
			}
		} elseif( !has_action('woocommerce_after_shop_loop_item_title', 'woocommerce_template_loop_price') && $WCFM->wcfm_has_catalog && apply_filters( 'wcfm_is_allow_add_to_cart_restore', true ) && !function_exists( 'rigid_related_products_args' ) && !function_exists( 'astra_header' ) && !function_exists( 'zita_post_loader' ) && !function_exists( 'oceanwp_get_sidebar' ) && !function_exists( 'x_get_stack' ) )
				add_action( 'woocommerce_after_shop_loop_item_title', 'woocommerce_template_loop_price', 10 );

These conditions belongs to each product on the loop, because not all products can have the same option value

I updated, the issue isn’t fixed. I checked your code and is wrong:

		if( $product_id ) {
			$is_catalog = ( get_post_meta( $product_id, '_catalog', true) == 'yes' ) ? 'yes' : '';
			if( $is_catalog == 'yes' ) { 
				$disable_price = ( get_post_meta( $product_id, 'disable_price', true) ) ? get_post_meta( $product_id, 'disable_price', true) : 'no';
				if( $disable_price == 'yes' ) {
					remove_action( 'woocommerce_after_shop_loop_item_title', 'woocommerce_template_loop_price', 10 );
				} elseif( !has_action('woocommerce_after_shop_loop_item_title', 'woocommerce_template_loop_price') ) {
					add_action( 'woocommerce_after_shop_loop_item_title', 'woocommerce_template_loop_price', 10 );
				}
			}
		}

The added/removed actions performs beyond the current product impression. When you modify the actions, you are modify the “routine actions” of the all loop.

Example:

Our loop has 3 products:
1- Price disabled: true
Then you remove de action
2- Price disabled: false
The action still removed
3- Price disabled: false
The action still removed

The logic of your code isn’t considering this fact

this isn’t resolved, you need update your files
i detected a new update, but the problem persist

I’m waiting

Another bug
changed condition get_post_meta( $product_id, 'disable_price', true) to get_post_meta( $product_id, 'disable_price', true) == 'yes'
