Trouble connecting a Dual Shock 4

I just downloaded the emulator and got a game on it. Every time I try to connect my Dual Shock 4 I get a fatal error message and the emulator closes out.  When I try to play the game with my keyboard, the game boots up, but the game only covers a portion of the screen.  I have the resolution scale matched with my computer.  I am running IntelUHD with vulkan.  Attached are two screenshots showing my problem.
