The reveal module doesn't show me any photos

When I have used on Macbook pro Lightroom 5 in the library module, I see all my imported photos. I choose one of them and go to the reveal module and that photograph appears to be able to make the adjustments. Perfect
I just upgraded LightRoom Classic on another new macbook when I do this and go to the module reveal photo nothing shows just gray background as if no photo. Can someone help me why is this and how can I solve it?
thank you so much

Go to Preferences - Performance and disable the use of the GPU (graphics processor). Does that solve it?
