Third party SDK returns incorrect value after notarizing my App

I'm facing a pretty weird issue. I have a function GetInfoA() which returns the value processed from the SDK API. Everything is normal until the app is notarized from Xcode. The value returned from GetInfoA() will be incorrect. I have NO idea why this happened because all the other functions from the API return the correct value, which means the SDK is working properly... right? Could anyone give me a hint on how to debug it? I'm clueless. Thanks in advance.
