Hi,
I am facing the same issue but i found one solution you replace the condition (woogst_get_woo_version_number() <= ‘3.7.0’) to (woogst_get_woo_version_number() >= ‘3.7.0’) in class-gst-woocommerce-addon.php file and this file location is plugins/woo-gst/class-gst-woocommerce-addon.php and line no 172. I hope this helps you.
