Hi @markm34441459 could you share some more info on what is happening? What workflow, steps, are you trying to do and what keys/shortcuts are you trying to use that are not working?
Launch BETA Photoshop While Pressing The Keyboard Shortcut
With Photoshop closed, press and hold Shift+Ctrl+Alt (Win) / Shift+Command+Option (Mac) on your keyboard and then Launch Photoshop the way you normally would.
