If restarting is not working for you, go to your start menu, type cmd and right click "execute as administrator", then type in the console "sfc /scannow" (without the "") in order to repair corrupted system files.
When is completed 100%, go to your local files in steamapps/common/dead by daylight and reinstall or repair EAC with the easyanticheat_setup.exe, then restart your pc.
Thats what I did with your same error after using WKE and the error is gone.
