Hello I wrote some code which fixes an issue:

	if( is_product() ) {
		$permalinks = wc_get_permalink_structure();
		$current_title = end($breadcrumb)[0];
		if ( $_SERVER['HTTP_REFERER'] ) {
			$url_parts = explode( '/', trim( wp_parse_url( $_SERVER['HTTP_REFERER'] )['path'], '/' ) );
			$url = site_url() . '/' . $permalinks['category_base'];
			$breadcrumb = array(
				array( __( 'Homepage', 'woocommerce-multilingual' ), site_url(), ),
				array( __( 'Catalog', 'woocommerce' ), site_url() . $permalinks['product_base'] . '/', ),
			);
			foreach( $url_parts as $url_part ) {
				if( $term = get_term_by( 'slug', $url_part, 'product_cat' ) ) {
					$url .= '/' . $url_part;
					$breadcrumb[] = array( $term->name, $url );
				}
			}
			$breadcrumb[] = array( $current_title );
		} else {
			$breadcrumb = array(
				array( __( 'Homepage', 'woocommerce-multilingual' ), site_url(), ),
				array( __( 'Products', 'woocommerce-multilingual' ), site_url() . $permalinks['product_base'] . '/', ),
				array( $current_title ),
			);
		}
	}

You should put it in ‘your_theme/woocommerce/global/breadcrumb.php’ just after ‘if ( ! empty( $breadcrumb ) ) {‘.

Hope it’ll help.
