❔ Building a delegate with a Type and a MethodInfo keeps throwing ArgumentException

public System.Delegate CreateRemoveMethod(System.Type elementType, System.Reflection.MethodInfo methodInfo)
        {
            if (methodInfo == null)
            {
                return null;
            }

            System.Reflection.ParameterInfo[] parameters = methodInfo.GetParameters();
            if (parameters.Length != 1 && parameters[0].ParameterType != elementType)
            {
                return null;
            }

            var action = typeof(System.Action<>).MakeGenericType(elementType);
            return methodInfo.CreateDelegate(action);
        }
