Thumbnails in Layers panel aren't showing images
I am using the latest version of PS 2020. For some reason, the thumbnails in my layers panel don't show any images. They are just gray and white squared, like a transparent layer, even though they aren't. So it's very hard to tell which layer is which, as often, there are many images in one file. I have searched online for how to fix this, but haven't seen anything. Have any of you encountered this problem? If so, how do I fix it?
