Unity IAP 4.1.4: Internal nullpointer exception in PurchasesResultBridge.getPurchasesList

Hi team,

We are seeing a spike in nullpointer exceptions triggered by a call to com.unity3d.services.store.gpbl.bridges.PurchasesResultBridge.getPurchasesList on OnActivity resumed. We are not making any calls to this explicitly, and it appears to be a normal internal process run by the IAP LifeCycleManager. This is occurring in the latest Unity IAP version (4.1.4) on Unity 2021.3.2f1.

We are unable to reproduce this in development, but receive a sharp incidence of crashes on a very small rollout (even at a super limited rollout of 600 users we're seeing 20+ crashes within hours).

I can't seem to find this crash appearing on Google yet, so if others are experiencing this hopefully it will be a focal point. Stacktrace below.

In my game, Pressing on any IAP causes direct crash with no error. Using the same IAP version 4.1.4. Any ideas on fixing this issue as well?
