I have no direct simple solution, I'll explain.
This file is only wrote by SexScripts main process. It is never read. Writing happens every 10 minutes if the editor is open. I checked the related code : simple, no obvious problem.
The error is : another process (of the same software or another) is writing in it at the same time (using the file mapping APIs - hsared memory). It is Windows related.
The most probable cause I see : an virus scanner, or two, open it for something. That can be also a virus itself that cause this (less probable).
You may also add this line at the end of
data.properties (then save it and relaunch SexScripts), that will stop the autosaver :
Code:
application.editor.assistlevel = 254
