app crashes updating to Xcode 11.2 from 11.1

My app ran without any crashes while using Xcode 11.1. After updating to XCode 11.2, my app experienced a crash:

*** Terminating app due to uncaught exception 'NSInvalidUnarchiveOperationException', reason: 'Could not instantiate class named _UITextLayoutView because no class named _UITextLayoutView 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)'

This crash seems to occur during a perpare for seque, before any of my views appear on the screen.

Any idea on the cause or solution?

Thanks.
