Conflict with other plugin (stock per country or zone)

Hello, Hope that all is well, kindly note that I was testing my new website using VPN in Egypt where the price should be fixed and showed with Egyptian currency by using your plugin, also, kindly note that Egypt has different stock from other country, I am using this plugin to determine the stock based on the customer location: https://stockmanagementlabs.com/addons/atum-multi-inventory/.

The two plugins are causing a fatal error when trying to check out as user located in Egypt, and your plugin is preventing to show the right stock in Egypt. Could you please solve this issue ASAP?
