Strange behavior and log entries for Mac Catalyst Action

I have a text based action for iPhone and Mac Catalyst I am developing in Xcode 14.3.1 on macOS 13.4.1.

I have the container app, an action and an AppGroup defined. I have confirmed that I can read the necessary shared defaults when the action launches. At this point the UI for the action is a simple textview in which I hope to display a modified version of the text passed to the action in the NSExtensionItems.

I am not using a simulator. I am running the action directly using Xcode.

What is happening is that the ActionViewController viewDidLoad runs but no visible window opens. In the console I see this as the action launches:

2023-07-05 18:27:23.692277-0700 XYZ[4634:279295] [ViewBridge] ViewBridge attempted to look up a hosted window with identifier 8E816BD5-67D3-402D-ADEB-AC59EDFA1F3B, but it was never registered.
2023-07-05 18:27:23.692408-0700 XYZ[4634:279295] [WindowHosting] UIScene property of UINSSceneViewController was accessed before it was set.
....

The last line above is repeated 12 times.... Any helpful ideas would be deeply appreciated! Steve

I have seen "UIScene property of UINSSceneViewController was accessed before it was set" log entry in myMac Catalyst app as well. I have been trying to track it down literally for months. If I find anything I'll post it.
