Hydraflow Hydrographs Extension error with the Windows 10 Spring Update (1803)

An issue has been noted when using the Hydraflow Hydrographs Extension in Civil 3D along with the new Windows 10 Spring Update that started rolling out in April of this year:

When computing the total outflow of a culvert/orifice of a pond model, the total outflow numbers continue to increase every time the "Compute" button is selected, instead of resetting to zero for each iteration.

Currently, the only way to fix this issue is to revert back to the previous version of Windows 10. Autodesk has been made aware of this issue, but as of the time of this blog post, no current hotfix or update has been issued.  I will update this post as soon as a fix is available.
