Hello IMA SDK team,

Recently we have observed some iOS 18/iPadOS 18 only crashes happening with NSAttributedString logged on Firebase Crashlytics:

Fatal Exception: NSInvalidArgumentException

Crash point to be:

- Foundation -[NSPlaceholderMutableString initWithBytes:length:encoding:] OR

- 

static Measurement<>.FormatStyle.UnitWidth.abbreviated.getter

(Full log attached below for investigation.)

We would like to understand if the team is aware of this issue yet? And is there any plan to release a newer version of the SDK for iOS 18+ support?

Thanks,

Yichen
