Error during update to WP 6.5.5 / WC 9.0.2

Error occurred while performing an update to the plugin (version 3.1.6):

PHP Fatal error: Uncaught Error: Call to a member function is_available() on null in .../wp-content/plugins/woocommerce-gateway-paypal-powered-by-braintree/includes/class-wc-gateway-braintree-blocks-support.php:51

Fix is relatively simple. Just add the following line (#51) in WC_Gateway_Braintree_Blocks_Support::is_active:

if ( !isset( $payment_gateways[ $this->name ] ) || is_null( $payment_gateways[ $this->name ] ) ) return false;
