get error message when loading "Your tool options bar will be clipped because your monitor scale factor is too large. Reduce your monitor settings to a lower scale, or drag Photoshop to a larger monitor." OK, it provides two solutions to said problem. The first solution creates its own problems in editing photographs, and the second costs $100s more.
But why the problem to begin with? This on a standard Dell laptop running at its native 3200x1800 resolution. When it opens (and it opens much more slowly than before the update), the panels don't display correctly, it won't switch between "maximize" and "restore" (MS's terms) properly, etc. Please fix.
