After Using Preset on an Image, the image preview goes black?

Working on an image in Lightroom - I click on one of my presets in the left column, and then the preview goes totally black?   Thank you!!

Only that one Preset? 

Here are a few options you can try:

First, disable GPU in preferences, any difference? 

If not, try resetting your Lightroom preferences:

Quit Lightroom Classic.
macOS: Press and hold the Shift + Option keys.
While holding down the keys, launch Lightroom Classic.
When asked, select "Yes".

Thank you for this great info and reply. I will try it now and let you know if it works!  Thank you!!

The first thing - disable GPU - seemed to make it work again.   Should I just leave that setting off permanently?  Is there any downside to leaving that off?

Thank you so much!!

If turning OFF GPU works, it's a GPU bug and you need to contact the manufacturer or find out if there's an updated driver for it. This is why disabling GPU is an option as more and more functionality moves to the GPU in newer versions of many Adobe products.
