I tried the Ultra quality for the graphics then the game crashed. Now the game get stucks on startup and then crashes again after a few minutes. Then I'll see the pop up: Game Security Violation Detected (#00000022). Please help! :(

Hey! Replying a bit late but I hope I can still help you.

You could try doing this:

1 - Press the Windows logo button + R

2 - Write %localappdata% in the text box and enter

3 - Go to DeadByDaylight > Saved > Config > WindowsNoEditor

4 - Delete Engine.ini and GameUserSettings.ini

I guess that restarting the game should create those files once again with the default values. The game shouldn't be set to Ultra settings anymore and your computer should be able to start it.
