I am getting an error when I try to ungroup (after having grouped a using a column). When I click the "X" I see this error being logged:
System.InvalidOperationException: Failed to compare two elements in the array.
---> System.ArgumentException: At least one object must implement IComparable.

at Microsoft.AspNetCore.Components.Rendering.ComponentState.RenderIntoBatch(RenderBatchBuilder batchBuilder, RenderFragment renderFragment, Exception& renderFragmentException)
The exception is not thrown in my code nor in the DataGrid's code.
When virtualization is OFF, ungrouping works OK and no errors are logged.
I have tested using the demos and it seems to be working OK without any errors.
I'd appreciate some advise as to how can I fix this?
If you can prepare for us small example demonstrating the problem we will be able to provide more info. It's possible also to attach Radzen.Blazor.csproj to your project and debug the code to check what's causing the exception.

This started happening when I took Blazor Server app that I hadn't worked on for some months and upgraded all nuget packages. Radzen.Blazor 4.29.9
