Launcher still is failing now mods won't work

Issue Summary: The VT2 launcher is failing to load still even after the latest patch for me. Bypassing the launcher - presumably due to the mods not all being up to date - means my game is buggy.

So now I’m stuck with mods I can’t disable (I can’t really even find where they are marked enabled in the config files if this info available that’d be good).

Note the launcher was broken last patch, I was hoping this patch would fix it. Using Windows 10 Professional. No other programs have any issues.

Steps to Reproduce:

  1. Launch the launcher

Mods are enabled/disabled in the config file here:

AppData\Roaming\Fatshark\Vermintide 2

in

user_settings.config

I’d suggest unsubbing to all mods and deleting the entire Vermintide 2 folder in App data, then verifying the game files in Steam. This will clear out some local settings, like keybinds and the like and your video settings too, as well as perhaps putting you in the prologue next time you run the game (which you can leave the moment you gain control of Kruber).

Thanks for the tips, didn’t know it was in AppData. I’ll clear out my stuff so mods don’t crash me and at least then I can play the game with glowy eyes.

Hope the .NET app can be a bit more solid in the future though, glad you have bypass enabled though.

I got annoyed after having no mods so went hunting for the bug - based on the errors above I found the UserControlLibrary.dll file in common\Warhammer Vermintide 2\launcher

I renamed it to UserControlLibrary.dll.old and revalidated it to redownload.

Magically it’s fixed. File is identical - according to the MD5 and SHA1 hashes. I have even disabled Windows Defender so no idea what was blocking / stopping / messing this up. Man Windows 10 is just bizarre.

Next time I might reinstall the game from scratch - full delete of the entire directory after removal too.
