I also ran into this question and solved it with some modifications to the answer given earlier. Maybe it will help someone.

function fetch_large_slider($postId) {
	$slider_images = [];
	$pid = (empty($postId) ? get_post() : $postId);

	// check if acf is used
	if (function_exists('get_field')) {
		if (has_blocks($pid)) {
			$blocks = parse_blocks( $pid->post_content );

			// run trough acf gutenberg/acf-blocks and find the right one
			foreach ( $blocks as $block ) {
				// find all selected images
				if ($block["blockName"] == 'acf/full-page-slider') {
					// build new array from found images
					$image_set = $block["attrs"]["data"]["fullpage_slider_images"];
					// collect image urls inside an array
					foreach ($image_set as $imageID) {
						$slider_images[] = wp_get_attachment_image_src($imageID,'full',false)[0];
					}
				} else {
					continue;
				}
			}
		}
	}
	return $slider_images;
}
