Bug Unity IAP throws an error when testing in UWP, causing the app to not work

Hi, i'm currently developing an app and I was testing it in the UWP platform. Everything is working fine except the IAP. The error that pops up is the following:


I'm using Unity 2021.3.17f and for IAP the version 4.8.0. I've read here (https://forum.unity.com/threads/unity-iap-does-not-work-on-uwp-platform.1104763/) that the best option is to go back to 2.2.2, but this is not really an option for me.

Any suggestion would be much appreciated!

 

This might help...
