Reset your preferences.

If you need a quick and dirty way to restore your preferences, here's a way you can do it using a keyboard shortcut on launch:

Windows - double-click the PS icon to start Photoshop

                  Immediately Hold down CTRL-SHIFT-ALT

                  You will see a delete preferences dialog. Click “yes".

Macintosh - Hold down CMD-SHIFT-OPTION instead.

or with CC

Hello, what version of Photoshop are you using?

(check in help>System info...)

Do try the preferences reset.

Maybe you unexpectedly changed your keyboard?

Shift+Ctrl on windows may change your keybourd layouty by default
