SfDataGrid crashes on initialization when Theme is applied

When using Theme in ResourceDictionary accordingly to documentation, sfDataGrid crashes application. Dark or light theme, with or without binding to data, doesn't matter, grid crashes . I have tried grid with own DataGridStyle and still crashes. Any suggestions? Thank you

app.xaml:

xmlns:syncTheme="clr-namespace:Syncfusion.XForms.Themes;assembly=Syncfusion.Core.XForms"

    <Application.Resources>
        <ResourceDictionary>
            <ResourceDictionary.MergedDictionaries>
                <syncTheme:SyncfusionThemeDictionary>
                    <syncTheme:SyncfusionThemeDictionary.MergedDictionaries>
                        <syncTheme:DarkTheme />
                    </syncTheme:SyncfusionThemeDictionary.MergedDictionaries>
                </syncTheme:SyncfusionThemeDictionary>

Exception:
