Thanks for reporting this issue. It's caused by an old "using" statement that should have been removed when we upgraded to the System.Text.Json serializing library almost two years ago. It's interesting that this is not a problem under any of the other versions of the .NET framework that we support, only .NET 8.

Anyway, I'll get this fixed and publish an update as soon as I can.
