CoreDataCloudKitDemo fails when creating a new Tag

I am running the demo on an actual device running beta 1 of iOS 15 and every time I go to add a tag I get these errors in the log. Any thoughts on what I am doing wrong or is there a bug in the demo code?

Thanks,

Rob

Actual Error:

    )

), NSUnderlyingException= threw while encoding a value.}

I believe it might have something to do with NSSecureUnarchiveFromDataTransformerName, Core Data and CloudKit with NSPersistentCloudKitContainer. But I don't know why this would be in the unmodified demo from Apple?

Any help much appreciated.
