SfDataGrid crashes on initialization when Theme is applied

[Michal]

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:
