@jbuchman and @buchmanj can you please help on this.

Can you provide more details how this crash occurred? Is this a custom app or one of the sample apps? If a custom app, how is the sdk integrated? Do you have a full crashlog? Can you provide an example project that demonstrates the issue?

We have integrated the library using pod. The version of IBMMobilePush is 3.6.0.12. Swift 5 version is used. We also tried installing AcousticMobilePush SDK through cocoapod but it is giving error while importing so I am unable to access its methods.

We found the following issue on firebase crashlytics

This repo contains cocoa pod integration up to version 3.7.1.4.1, have you tried using that version? Have you tried integrating using the AcousticMobilePush.xcframework instead of cocoa pods? Have you tried integrating use the IBMMobilePush.framework instead of cocoa pods? Is this crash happening on first startup? On a fresh install? After some specific method call?
