Critical errors when previewing WooCommerce emails (missing test data)

When using the WooCommerce email preview feature (WooCommerce > Settings > Emails > Preview), the SUBRE Product Subscription for Woo plugin throws critical PHP errors because no actual subscription or order data is available in that preview context.

Examples A:

File: includes/data.php
Issue: new WC_DateTime(“@{$timestamp}”) is called with an empty $timestamp, causing Failed to parse time string (@).

Missing check like:

if ( empty( $timestamp ) ) return new WC_DateTime('now');

or return null when no timestamp is provided.

Examples B:

File: includes/subscription-order.php (around line 862)
Issue: $subscription->get_payment_method() is called on false when wc_get_order() returns false (because no order exists in preview mode).

Missing check like:

if ( $subscription && is_a( $subscription, 'WC_Order' ) ) {
…
}
