Security updates are separate from the general OS updates. While I don't want the system to update behind my back, the security updates are another matter.
I suggest you keep those on: System Preferences->Software Update->Advanced...
This may not be directly related to the problem in this thread, but still it is important.
Also, the battery appears to not be ih good condition. This, besides not having a long battery life, can in time cause other issues, so if you plan on keeping this mac for a few years still, it may be worth considering a new battery.
Here is something that you can try - it may not help (probably), but it can't hurt. In Finder->Preferences->Sidebar, UNcheck the box for iCloud Drive; try to save something - you won't see iCloud Drive, naturally. Check that box again, and try. Any changes?
