I wasn’t suggesting it was because of the version. I had the same issue in 10.2.x and I have no reason to believe it was ever fixed. In fact, I reported it and was told that support wouldn’t even pass it along to the developers because there were no clear steps to reproduce, and because the workaround of deleting the cache exists. The problem with the client sometimes randomly exiting without error persists to the present day in Kinetic cloud.
There are other serious bugs related to the cache or worked around by deleting it. For example, if you customize a UI form, weeks or months later, a few users will randomly start seeing the old version of the form. Deleting their cache fixes it for a while, then the old version mysteriously reappears again.
