Hey, @default43275222ao3hva. Welcome to the Photoshop Community. As @Jeff Arola said, we'll need more information to help you figure this out.
The user interface looks like Photoshop on the Web in Light mode. The image in the screenshot might be corrupted. Do you see the black screen & grid pattern with every document you work with?
Has this started to happen with a set of images? What Web browser are you working on?
Let me know how it goes. Thanks!
