Looking at your stack trace, it doesn't look like this crash is specific to the Braze code since it looks like the crash occurs from code in Foundation when trying to update the views. Are you doing any customizations in how you display in-app messages? If you are seeing this crash a lot, it is likely due to customizations.
Our app meet a lot crash, i check crash log, the reason seem is layout engine performed from a background. could you help check it?
