WaitForSingleObject failed:2

I have multiple solutions for the
EAC Error 30004 WaitForSingleObject Failed Error: 2

First of all "sfc /scannow" will work sometimes, so try it first.
You can Reinstall DbD too, or you can run EAC and DbD as an administrator.
when the Error still appears follow the next steps.

1. Do all Windows Updates - Didnt work? Next step
2. Update your Hardware (Graphic, Mainboard (sometimes), ...) - No? Next
3. Reinstall EAC -> Go to your DbD folder and delete the EAC setup and you need to delete your EAC installed folder (in program files),
   after you need to repair the game (in steam u can repair it in the settings of DbD, rightclick on the game and go to the settings) - Still dont work?
4. Try to delete the sys data from EAC
   C:\Windows\System32\drivers and search for EasyAntiCheat.sys (make a copy of it on your desktop to be sure you dont loose it)
   if you can run it now, delete the file on your desktop - It still wont to work???
5. Open cmd in Windows as an administrator
   now you write following commands first:
   1. bcdedit.exe -set TESTSIGNING OFF
   2. bcdedit.exe -set NOINTEGRITYCHECKS OFF
   now you need to restart your computer.
   
   If the Error still appears you need to Reinstall Windows 10, Error 30004 appears than because your Windows is corrupted.

I hope it will work for some people! Good luck!
