It has Selenium 26 in it. I get this:
System.NotSupportedException : JsonTypeInfo metadata for type ‘System.Text.Json.JsonElement’ was not provided by TypeInfoResolver of type ‘OpenQA.Selenium.CommandJsonSerializerContext’. If using source generation, ensure that all root types passed to the serializer have been annotated with ‘JsonSerializableAttribute’, along with any types that might be serialized polymorphically. The unsupported member type is located on type ‘System.Object’. Path: $.

If anyone is aware of what this needs I am more than happy to fix it but I have made changes to the existing JSON and everything else and no change what.
