This is from me deploying to a Win10 19041 VM.

Closed a second window, then hovered over the first. At some point got:

>	Windows.UI.Xaml.Controls.dll!winrt::throw_hresult(const winrt::hresult result) Line 4524	C++
 	[Inline Frame] Windows.UI.Xaml.Controls.dll!winrt::check_hresult(winrt::hresult) Line 4612	C++
 	Windows.UI.Xaml.Controls.dll!winrt::impl::consume_Windows_UI_Xaml_IDependencyObject<AcrylicBrush>::GetValue(const winrt::Windows::UI::Xaml::DependencyProperty & dp) Line 1045	C++
 	[Inline Frame] Windows.UI.Xaml.Controls.dll!AcrylicBrushProperties::AlwaysUseFallback() Line 150	C++
 	Windows.UI.Xaml.Controls.dll!AcrylicBrush::UpdateAcrylicBrush() Line 996	C++
    ...

This one's a hard failfast that can't be continued. Window also seems to be in a normal state? In a normal _messagePump?

This happens every time I hover the split button after closing another window on Windows 10, but not on Windows 11.
