Conflict with Custom Order Statuses for WooCommerce

Hello there,

I have discovered that your plugin is conflicting with Custom Order Statuses plugin.

It produces a critical error on the order status update. This is what I have captured:

WooCommerce\PayPalCommerce\WcGateway\Gateway\PayUponInvoice\PayUponInvoice::WooCommerce\PayPalCommerce\WcGateway\Gateway\PayUponInvoice\{closure}(): Argument #4 ($email) must be of type WC_Email, string given, called in /home/mydomainname.com/asdasdasdsdkpvhpubjec/public_html/wp-includes/class-wp-hook.php on line 308
in /home/mydomainname.com/asdasdasdsdkpvhpubjec/public_html/wp-content/plugins/woocommerce-paypal-payments/modules/ppcp-wc-gateway/src/Gateway/PayUponInvoice/PayUponInvoice.php on line 286
