Recent Version(s) Periodically Shut-Down Without Explanation

In many of the recent versions, particularly, it seems, during the “Save File” process, the application just “Quits/Exits” without any indicatio as to why. The application is running as a standalone product so shouldn’t be affected by any other integrated applications (e.g. Lightroom, Photoshop, etc.). The application starts up right away upon icon re-initiation and operates normally . . at least until the next unexplainable shut-down.
