I was dealing with this same issue today after the last TT update. I had no issues when I used the application (W10) in Feb/19. But the update today 3/31 may have been the issue. After reading some of the remedies, I tried the W8 compatibility setting, but that didn't fix the issue. The other suggested remedy, running as Admin, appeared to have fixed the issue. It could very well be the combination of both. I didn't go back to see about removing the W8 compatibility setting.
