Try resetting your Photoshop Tools and if that does not work try resetting your preferences. It seem the are two properties panel in Photoshop. Select and mask properties seems to be separate from menu window>Properties.
I can get that small properties panel by opening through Window tab. But I cant get the whole other panel that you have on your screen which gives all the other options. I used to have it and now I don't. I can literally go on "select and mask" but I cant do anything. i cant even exit bc I don't have the panel so I cant press "ok" or "cancel". So how I can I get it back?
