"Hi, I'm just a user, but I've had problems with DS4.
Try to check these points, it might help:
1 - Unistall DS4 Windows / InputMapper / ScpToolkit (if you have it)
2 - Unistall or Disable Xpadder (if you have it)
3 - Check if your antivirus is not running DLLs in “sandbox” (Try to disable it to test)
4 - Run the Emulator as administrator
5 - Try cable connection "

6 - Try changing the Handler


I hope it works for you
