Error 3711 when clicking Add Item in Purchase Order after Windows 10 April Update

Hi there,

I am getting intermittent error ("Run-time error '3711': Operation cannot be performed while executing asynchronously") when clicking on Add Item in Purchase Order. It only happens on computers updated to Windows 10 2018 April update. Other machines are running fine. My SQL server has plenty of RAM assigned.

SQL Server 2014 Standard SP4

Windows 10 PRO 

RMS Ver 2.0.2022
