Hi Francis,
I'm Dave, I'll help you with this.
This is a widely reported bug in the latest Photo update, many people have reported the same problem, hopefully Microsoft will fix this update soon because there is nothing wrong with your computer, we have to wait for them to resolve it.
The best option is to open the Feedback Hub (Windows Key + F) and report it there, the more people report this problem, the sooner it will be fixed.
