that code is indicating the anti cheat is supposedly blocked.
maybe they added a heartbeat check to the game to look for it.
if so, then it means you are stuck with them hijacking and manipulating your operating system kernel if you want to play a video game, even if you want to play alone, and by yourself.
if mods and trainers and being able to play a game without something literally hijacking your OS and preventing you from doing stuff with your own operating system on your own computer, then the way to respond to this is to not buy vermintide 3 or anything else that uses these root kit type methods to jack up your computer for video games. It's not like you are working at a swiss bank and that it's some computer system in charge of trillions of dollars. You are playing a fake character on a video game.
If everyone is getting error 30005 after some time, then you are either doing it wrong, or there is some other check in place now to thwart you recovering your operating system.
Trainer works. WKE is blocked from working. Don't get it twisted.
Well this means the party is over. Contact maker of WKE to see if they can release a new version to prevent detection, otherwise you have to wait for windows 10 update that forces new WKE version.
Until then, Vermintide 2 is not playable with trainers or mods and your operating system is hijacked at the kernel level by EAC, for a video game.
I have no control over this. If EAC and the developers of this game don't want you to be able to undo the way the hijack your operating system on your own machine by banning tools that allow you to remove rootkits and hijacked OS, then I cannot help you.
Trainer still works on non-official servers/games so we will leave it in place.
duly noted but not going to try and recode a difficult trainer when people can just turn this off while doing that.
