It looks like proguard misconfiguration

It looks like proguard misconfiguration

What is the specific configuration of proguard?

I've also encountered this issue. I checked the source code and found that MeasurementManager was likely introduced in API 34 or SdkExtension 4 (see https://developer.android.com/design-for-safety/privacy-sandbox/reference/adservices/measurement/MeasurementManager?hl=en-us), but OutcomeReceiver wasn't introduced until API 31. On some Android 11 (API 30) devices with SdkExtension >= 4, the MeasurementManager class may exist, but OutcomeReceiver may not.

Is there any update on this issue ? I am facing issues in my production app with this as well.
