Cult of the Lamb – How to Fix Black Screen Bug

This guide helps you on how to fix black screen issues (bugs) in Cult of the Lamb.

How to Fix Black Screen Bug

This is a workaround fix for anyone suffering from the black screen bug, which prevents you from playing by showing a black screen after the Massive Monster logo, or after receiving the Red Crown.

Black Screen Workaround Fix


So I see many posting still about the infamous black screen bug which prevents someone from playing after starting the game, or after getting the crown from the One Who Waits.

The reason these occur is both of these events trigger a video to play once they occur, one being the Devolver Digital logo, and the other being the Intro cinematic where the lamb gets the Red Crown.

The issue is, is that currently, video playback is bugged, and the video won’t play.

However, the game won’t progress until it registers that the video, has finished playing.

The video can’t play, but the game is waiting for it to finish, so you get a black screen and a soft lock.

So, after suffering this problem myself, and with the help of others in a discussion on a Tech Support thread, I managed to reverse engineer one of the .dll files and make a simple fix, so that you can bypass these issues until an official patch fixing these issues comes out.

How to Apply Workaround

So, it really isn’t too difficult. I didn’t do much, after all, it’s just a quick file replacement.

Simple run-through:

  • Check which fix you need.
  • Download the .dll file from the link.
  • Replace the matching .dll in the Cult of the Lamb game files under the ‘Managed’ folder.
  • Start game.
  • That’s it!

Detailed run-through:

Okay so if you’re not the most technically inclined the above might be an oversimplification, so just follow here for more detail.

  1. Identify which fix you require
  • First, you need to check which fix you need.
  • The first fix skips the Devolver Digital splash logo, and the Intro cinematic after receiving the Red Crown.
  • The second fix skips only the Intro cinematic after receiving the Red Crown.
  • In a nutshell, if you are only getting a black screen after the Massive Monster logo, get the first fix.
  • If you are getting a black screen only after reviewing the Red Crown from the One Who Waits, get the second fix.
  • If you don’t know, get the first fix.
  1. Download the .dll file
  • Below I’ve provided some links to the file you need. They’re called .dll files, but you don’t need to worry about what they are.
  • The link will take you to my google drive folder, simply right-click and download the one you need.
  1. Navigate to the correct folder

The folder you’ll need to get to is the ‘Managed’ folder in the game files. There are two ways to get to it.

You can either get to it through Steam:

  • Right-click the game on Steam.
  • Go on ‘Properties’.
  • Go on ‘Local Files’.
  • Go on ‘Browse…’.
  • Open “Cult Of The Lamb_Data”.
  • Open “Managed”.

Or you can just navigate through File Explorer to get to it.

Simply go to:

  • “C:\Program Files (x86)\Steam\steamapps\common\Cult of the Lamb\Cult Of The Lamb_Data\Managed”

Note: Providing you have the game installed on your C: drive, if not, simply replace the drive letter of course.

  1. Replace the file
  • After reaching this folder, simply copy the file you downloaded here.
  • It’ll prompt you, asking if you want to replace or skip files.
  • Click ‘Replace the file in the destination’.
  1. Start the game

That’s it! Start the game!

Assuming you were doing this while the game was closed, if not, just restart it.

Fix 1

Fix 2


These fixes are only for until the official patch comes out that fixes these problems.

Of course, when the patch does come out, it’ll automatically replace the file you change so you don’t need to reverse it or anything.

That being said, this means that whenever a patch comes out, this file will be reverted.

If a patch comes out that does not fix the black screen problem, you will need to replace this file again.

Also, I really doubt this will do anything to your save game, but given how many bugs there are at the time of writing this, you might want to backup your save file, just in case a patch comes out that fixes it that…somehow causes an issue? It would make little sense if it did but, just in case.

This is good practice anyway, in case the other infamous bug occurs that basically permanently corrupts your save happens.

To go to:

  • ‘C:\Users\%USERNAME%\AppData\LocalLow\Massive Monster\Cult Of The Lamb’

Make sure to replace %USERNAME% with your own username.

Once here just copy the entire ‘saves’ folder somewhere else, as a backup.

Make sure to do this somewhat regularly of course.

Be careful though. If you accidentally delete this folder, your save is gone.

And if you can’t get it back via the Recycle Bin or something, it’s gone for good.

I am not responsible if you somehow ♥♥♥♥ up and delete your save. Please exercise lots of caution when fiddling with save game files.
