@davidi67 , But did you do the suggested fix for that, before uninstalling and installing an older unsupported version to see if that would work. Since the original poster never responded here, it’s unclear if that fixed the problem, and your not trying to use the fix, amounts to the same lack of knowledge this issue still presents. I haven’t had any problems so it doesn’t affect me, but others having the same issue might like to hear that you tried the fix and it worked or not, so they have a better idea of what to look for if that does or doesn’t fix it.

@Troglo37 Well, they already have a “auto-backup” feature, it just doesn’t target config files, only files you open in the editor and when you make changes to that file and haven’t closed it. I made my own program to just copy files, but I’m not ready to look at doing something that checks every possible setting for a comparison against original or recently changed config files that may have had only minor changes. I think that’s why something like this hasn’t been done yet. So many settings, AND between versions, the menu and the options may change as well, so if someone wrote such a program/plugin/feature, it would have to be constantly updated for when the Notepad++ program changes, as well.
