PHP Fatal Error

We’ve just had to disable the “EU/UK VAT for Woocommerce” plugin (version 2.11.8) from within recovery mode as we were unable to login to our admin dashboard as there was a critical error preventing access.  Our error logs point at the following fatal error coming from the EU/UK VAT plugin:

PHP Fatal error: Uncaught Error: Call to a member function meta_exists() on null in /home/XXXX/public_html/wp-content/plugins/woocommerce/includes/class-wc-checkout.php:1360\nStack trace:\n#0 /home/XXXX/public_html/wp-content/plugins/eu-vat-for-woocommerce/includes/class-alg-wc-eu-vat-core.php(1115): WC_Checkout->get_value()\n#1 /home/XXXX/public_html/wp-content/plugins/eu-vat-for-woocommerce/includes/class-alg-wc-eu-vat-core.php(204): Alg_WC_EU_VAT_Core->get_field_data()\n#2 /home/XXXX/public_html/wp-includes/class-wp-hook.php(324): Alg_WC_EU_VAT_Core->register_additional_checkout_block_field()\n#3 /home/XXXX/public_html/wp-includes/class-wp-hook.php(348): WP_Hook->apply_filters()\n#4 /home/XXXX/public_html/wp-includes/plugin.php(517): WP_Hook->do_action()

Is this a known issue with the current release and is there a way to fix this error?  In case it’s relevant, our WordPress version is 6.5.5.
