Application breaks on re-throw Exception Fody

Question

I am trying to handle all the exceptions thrown from a async method, but when i throw the exception after the execution of an async child method,then on re-throw exception from fody(OnException method) application breaks.

Like:

using MethodBoundaryAspect.Fody.Attributes;

public sealed class ExceptionHandlerAttribute : OnMethodBoundaryAspect
{

    public override void OnException(MethodExecutionArgs args)
    {
        //re-throw exception
        throw args.Exception;
    }
}

public class ClassName
{
    [ExceptionHandler]
    public async Task<T> MethodAsync()
    {
        //do some async work
        await OtherClass.DoSomeWorkAsync();
        throw new Exception("Exception after the execution of an Async method");
    }
}

public class ParentClass
{
    public async Task<T> MethodAsync()
    {
        try
        {
            ClassName className=new ClassName();
            await className.MethodAsync();
        }
        catch(Exception ex)
        {
        }
    }
}
