Whenever I launch the game through steam, the launcher works fine, but when I press play. The game crashes and gives me an error screen that Vermintide2_dx12.exe failed to launch 0xc0000142
Hm, perhaps try verifying integrity of game files:
Right-click Vermintide 2 in your Steam library sidebar
Select ‘Properties’
Select the ‘Local Files’ tab
Select the ‘Verify the Integrity of Game Files’ button
When complete, close and reopen Steam
Otherwise, are you able to launch successfully in Modded realm? (chosen from the launcher options). I ask, as EAC only applies to Official realm and this can help in isolating the issue.
If so, your Anti-Virus/Firewall may be interfering with the dx12 .exe file. So I’d recommend adding Anti-Virus and Firewall exceptions for the following:
vermintide2.exe in \Program Files (x86)\Steam\steamapps\common\Warhammer Vermintide 2\binaries
vermintide2_dx12.exe in \Program Files (x86)\Steam\steamapps\common\Warhammer Vermintide 2\binaries_dx12
EasyAntiCheat.exe in \Program Files (x86)\EasyAntiCheat
