The image icons in Finder>Pictures have all switched to generic icons. I checked Finder>View> to check view options but that was set correctly; then tried Activity Monitor to use com.apple.quicklook.ThumbnailsAgent to fix it, but that didn't work. But, when I relaunch in safe mode the icons show up correctly; back in regular launch, same problem.

That would tend to implicate some third-party system modification is interfering with you Mac. I don’t know what it might be.
