STJ failing ungracefully when attempting to serialize attributes #58947
Description
Discovered while investigating #58690. The code
using System;
using System.Text.Json;
JsonSerializer.Serialize(new MyAttribute());
public class MyAttribute : Attribute { }Throws the exception
Unhandled exception. System.InvalidOperationException: Method may only be called on a Type for which Type.IsGenericParameter is true.

Like #58690 this covers a niche use case, though we should still investigate the root cause and at least attempt to fail gracefully.
