Fatal Error after activating Aelia Currency Switcher integration

Hello,
after buying and installing Aelia Currency Switcher and activating the extension for Role Based Pricing, I’m getting the following fatal error while attempting to visit the front end of the site as an administrator. Note that the issue doesn’t seem to affect logged-out visitors or non-admin customers.

Fatal error: Uncaught Exception: Invalid product. in /{site_url}/wp-content/plugins/woocommerce/includes/data-stores/class-wc-product-data-store-cpt.php:163 Stack trace: #0 /{site_url}/wp-content/plugins/woocommerce/includes/class-wc-data-store.php(159): WC_Product_Data_Store_CPT->read(Object(WC_Product)) #1 /{site_url}/wp-content/plugins/woocommerce/includes/abstracts/abstract-wc-product.php(135): WC_Data_Store->read(Object(WC_Product)) #2 /{site_url}/wp-content/plugins/woocommerce-role-based-price/plugins/aelia-currencyswitcher-integration/aelia-currencyswitcher-integration.php(213): WC_Product->__construct(1509) #3 /{site_url}/wp-content/plugins/woocommerce-role-based-price/plugins/aelia-currencyswitcher-integration/aelia-currencyswitcher-integration.php(129): Aelia_Currency_Switcher_Integration_WC_RBP->get_acs_role_price('', 1509, 'administrator', 'selling_price') #4 /{site_url}/wp-includes/cla in /{site_url}/wp-content/plugins/woocommerce/includes/data-stores/class-wc-product-data-store-cpt.php on line 163
