I'm working on a Blazor project with .NET 6 framework and it works fine. I'm using Radzen too.
Since I go to .NET 8, I get a problem with grouping on a Radzen Grid. The grouping never ends and i get many errors messages in the Output window like this :

Do someone meet this king of trouble by updating to .NET 8 ?
I made a repair of Visual Studio 2022 but nothing changes.
I compare with Radzen tutorial and I see more dll in the debug folder but I don't know since I don't have those in my folder.
