How to Fix Cult of the Lamb: Woolhaven Crashing on Startup (DLC Launch Guide)

You pre-ordered the Woolhaven expansion, ready to meet Yngya and explore the frozen mountains. But the moment you click “Play” on launch day, the game freezes, throws a Unity error, or—worst of all—the DLC content simply doesn’t appear.

Launch Day Reality Check: Major updates like Woolhaven (v1.5+) almost always break existing mods and require specific file verifications.

Whether you are facing a black screen, a “Fatal Error,” or your cult save file won’t load, this guide covers the urgent fixes to get you into the snow.

Editor’s Warning: The #1 Cause of Crashes

Method 1: Disable Broken Mods (BepInEx)

Launch day crashes are 90% caused by outdated mods. Even if you “disabled” them in a manager, leftover DLL files can still hook into the game and crash it.

Method 2: Force Steam to Verify DLC Files

Sometimes Steam downloads the base game patch but “forgets” the DLC assets, causing a crash when the game tries to load the new Woolhaven assets.

1. Right-click Cult of the Lamb > Properties > DLC.
2. Uncheck and Re-check the box next to “Cult of the Lamb: Woolhaven”. This forces a download refresh.
3. Go to Installed Files and click “Verify integrity of game files”.

Method 3: Fix Unity “Citrix” & Display Errors

The “Woolhaven” update runs on an updated Unity engine version. If you get a UnityPlayer.dll error or a generic crash:

• Uninstall Citrix Workspace: This virtual display driver conflicts with Unity games. Uninstall it, restart PC, and try again.
• Delete Config File: Corrupted settings from the previous version can crash the new one.
  Go to: C:\Users\[User]\AppData\LocalLow\Massive Monster\Cult Of The Lamb\
  Delete Settings.json.

Method 4: Steam Deck Launch Issues

If Woolhaven crashes on your Steam Deck, specifically during the new dungeon transitions:

• Force Proton Experimental: Properties > Compatibility > Check “Force the use of a specific Steam Play compatibility tool” > Select Proton Experimental.
• V-Sync Fix: Some users report that disabling V-Sync prevents crashes during the new snow weather effects.

Method 5: “DLC Not Loading” (Fix)

Game starts but no Woolhaven content?

• Progress Check: The DLC content is usually accessible only after you have defeated at least two Bishops (or reached a specific mid-game milestone). It is not available on a fresh save file immediately.
• Region Check: Ensure your DLC purchase matches your base game’s region.

The Workaround: Skip the Grind with XMODhub

• Save Manager: Roll back to a pre-update backup if your save gets bugged.
