I have an issue when working with artboards in Photoshop in both 22.5 and 22.5.1. In both versions, I load a file with an artboard in it. There's a random black box on the artboard; when I try to get rid of it, the artboard itself disappears and Photoshop starts to lag. For files with actual content, it just looks like I'm working without an artboard when this happens. For empty artboards, everything in the working space disappears. This is rendering Photoshop nearly unusable.
