Crash: NSInvalidUnarchiveOperationException when decoding MPUploadSettings

[aaronmusa-candyspace]

Description

We’re seeing random crashes at runtime with the following exception:

*** Terminating app due to uncaught exception 'NSInvalidUnarchiveOperationException', reason: '*** -[NSKeyedUnarchiver decodeObjectForKey:]: cannot decode object of class (MPUploadSettings) for key (root) because no class named "MPUploadSettings" was found; the class needs to be defined in source code or linked in from a library (ensure the class is part of the correct target). If the class was renamed, use setClassName:forClass: to add a class translation mapping to NSKeyedUnarchiver'

This occurs randomly during app launch. It simply happens sporadically. It appears that the SDK is persisting an MPUploadSettings object, but sometimes cannot deserialize it later.

Steps to Reproduce

We don’t have a consistent reproduction path, but the crash occurs intermittently.

Additional Context

• We haven’t changed SDK versions between launches.
• Clearing app data (deleting/reinstalling the app) temporarily resolves the issue, but it recurs later.
• This suggests possible corruption or a race condition in the SDK’s persistence/unarchiving logic.
• We're using SPM as dependency manager

This is also happening to me on my project setup. We are running version 8.36.0

Seeing this on our project as well. Seems to happen consistently for a period of time and then resolves. We were on 8.31.0, updating to latest to see if there's any change

Hi @katmarshgriffin, did it resolve the issue? Which version did you update to?

@aaronmusa-candyspace Apologies for the late response. We haven't experienced the issue on 8.40.0
