Workaround: Add audio to the preview video in iMovie. Set the audio volume to 0. Export the video again and upload.

Still not fixed in Ventura 13.3. Can you show your code so I can see what's different from mine? I tried using it with a UIButton instead of UIBarButtonItem and then adding it to my NSToolbar with NSUIViewToolbarItem but still not working. The menu just shows a "Loading..." item and the uncached provider block is never called.

Another quick question: would it be considered intended behavior for two UIWindowScenes to have their activationState set to UISceneActivationStateForegroundActive at the same time?

It appears in AppKit land the expected NSWindow is the main window when the described issue occurs but in the Mac Catalyst world the wrong UIWindowScene has the foreground active state which is good news because that means a workaround should be possible.

Yes I was able to resolve it. So in my case I have a dedicated object as the UITableViewDataSource that sits between the UIViewController and the UITableView. The object that I use as the table view data source implements everything needed to populate the table view data, refreshing it automatically on model changes, etc. The only thing my table view data source doesn't do was provide a UITableView cell in -tableView:cellForRowAtIndexPath: method (instead it asks its delegate for the cell, which is the UIViewController) . My data source object is sort of like UITableViewDiffableDataSource in this way. So what was happening is the UITableView AND the table view data source objects were occasionally outliving the UIViewController. Then when a model change notification is posted my datasource object asked the view controller for the cell in -tableView:cellForRowAtIndexPath: (but the view controller was already deallocated). Never was able to reproduce it in debug mode. I removed the delegate-protocol from my data source object and captured the cell creation code in a block property and I haven't had a crash since.

Thanks for answering.

Also noticed copying multiple links to the pasteboard does not work on Mac Catalyst. [UIPasteboard generalPasteboard].URLs = @[appleDotComURL,websiteTwoURL,websiteThreeURL]; On iOS when I do that I can open "Notes" and paste and the strings for all three urls paste properly. But doing the same thing on Mac Catalyst it just pastes one url string...

This works better it seems: NSString *string = urlToCopy.absoluteString; NSArray *objects = (string != nil) ? @[urlToCopy,string] : @[urlToCopy]; [[UIPasteboard generalPasteboard] setObjects:objects]; Will have to remove WKWebViews default copy action.
