A client site suddenly started getting file I-o errors 92 on open I-o

yesterday "patch Tuesday"  November 10th 2020 , however they do not seem to have applied the recent patches.

Strange that 2 servers suddenly start behaving in this way.

Windows 2012 R2

Vision files version 9.2.3 acucobol running

Just putting it out there as it looks similar to the issue we had 2 years ago with windows server 2008 and windows 7 and the 9107 file error on open-close-delete
