engine crash when using c# native string to define property in dynamic class

I define the class as shown below

namespace Script.CoreUObject
{
    [UClass]
    public partial class BP_DynamicTest_C : AActor
    {
        [UProperty, BlueprintReadWrite] 
        public string Name { get; set; }

        [UFunction, BlueprintCallable]
        public void SetName(string InName)
        {
            Name = InName;
        }
    }
}
