Dashboard Layout crashes page in version 20.1.0.47 and above

Today i started to update my installed version of the Blazor Components form 19.4. to the current version (

20.1.0.51) after that my application stops with an error:

 Microsoft.AspNetCore.Components.Server.Circuits.CircuitHost[111]

      Unhandled exception in circuit 'sKqcRgca6TTvO1TjilPD8EgEHmGo-CJ2pIcLO0dnlS8'.

      System.ArgumentNullException: Value cannot be null. (Parameter 'json')

         at System.Text.Json.JsonSerializer.Deserialize[TValue](String json, JsonSerializerOptions options)

         at Syncfusion.Blazor.Layouts.SfDashboardLayout.Initialize()

         at Syncfusion.Blazor.Layouts.SfDashboardLayout.OnAfterScriptRendered()

         at Syncfusion.Blazor.SfBaseComponent.OnAfterRenderAsync(Boolean firstRender)

         at Syncfusion.Blazor.Layouts.SfDashboardLayout.OnAfterRenderAsync(Boolean firstRender)

         at Microsoft.AspNetCore.Components.RenderTree.Renderer.GetErrorHandledTask(Task taskToHandle, ComponentState owningComponentState)


after downgrading versions step by step everthing works fine
at version 19.4.X. So the first crash comes with 20.1.0.47.
I've tried these in a new blank project with the same results.
It seems its just actually this explicit component.
