Thank you @B4seUser
it is now fixed, and will be available soon with next version.

You’re getting that exception because MenuItemContainerStyle is applied to all generated menu containers inside NavigationView, not just NavigationViewItem.
that style is also applied to NavigationViewItemSeparator, and since its type is different, WinUI throws:

Cannot apply a Style with TargetType 'NavigationViewItem' to 'NavigationViewItemSeparator'
