iOS / iPad OS v15.0 opening "Test workspace" Help Center with SDK 16.3.1 crashes

Only my “Test workspace” crashes, the production one works fine.

The code I’m calling is the following when opening the Help Center:

Intercom.present(Space.helpCenter)

--

The uncaught exception that is being thrown is:

Terminating app due to uncaught exception 'NSUnknownKeyException', reason: '[<IntercomSDKPrivate.ErrorViewController ...> setValue:forUndefinedKey:]: this class is not key value coding-compliant for the key closeImageView.'

Which often means the `ErrorViewController.xib `(or storyboard?) had a property set in a XIB which longer exists in ErrorViewController.

--

The expected behaviour is that if an error needs to display (because I’m using a test workspace) that the error shows rather than the app crashing.
