Chrome 69 introduced a few changes, one of them apparently causes Window Snapping to break on some systems.
If you encounter this issue you should update to these betas of BetterSnapTool or BetterTouchTool. It would be great if you'd report whether they fix your issue, because unfortunately I haven't been able to reproduce it on my machines yet.
