Problem opening Photoshop after 2015.1.1 update. As app opens (while intro screen is visible) one receives the following error, "The operation could not be completed". Shortly thereafter the app briefly (maybe 5 to 7 seconds) shows blank gray screen (what you expect with app open yet no file open) with dropdown menu at top. Then it crashes (closes). Reinstall, startup with no 3rd party add-ons, and starting using Terminal have no effect. Others have reported issue with no solution other than to reinstall previous version (15.0).
