CRITICAL Uncaught Error: Call to a member function get()

Hi,

I’m facing this error when i go to my admin dashboard > Woocommerce.

An error of type E_ERROR was caused in line 96 of the file /home/delwynta/public_html/theaislemarket.com/wp-content/plugins/woocommerce/includes/data-stores/class-wc-customer-data-store-session.php. Error message: Uncaught Error: Call to a member function get() on null in /home/delwynta/public_html/theaislemarket.com/wp-content/plugins/woocommerce/includes/data-stores/class-wc-customer-data-store-session.php:96

#4 /home/delwynta/public_html/theaislemarket.com/wp-content/themes/urna/inc/vendors/woocommerce/wc-single-functions.php(850): WC_Checkout->get_checkout_fields()
#5

Does it seems like it has something to do with “billing_country” field?

I’m using “Checkout Field Editor for WooCommerce” plugin, but i did not use the plugin to edit the “billing_country” field”.
Hence, i’m not sure whether is this Plugin thats causing the issue.

Please assist.

This is an extract of Line 88 to Line 96 of the “class-wc-customer-data-store-session.php” file.

/**
* Read customer data from the session unless the user has logged in, in
* which case the stored ID will differ from the actual ID.
*
* @since 3.0.0
* @param WC_Customer $customer Customer object.
*/
public function read( &$customer ) {
$data = (array) WC()->session->get( ‘customer’ );

Also, here’s the system report for woocommerce:
