Fixing the Back 4 Blood crash at launch issue

The game is running well for the most part, and the beta led to positive reception as well. The game has some options to tweak as well to get some more frames and is overall a decent PC release. However, a few users have reported some issues, namely the game crashing at launch. To fix this, you can try some of the following suggestions.

Disable Webroot Anti-virus

Windows 7 Users – Disable Sharpening

If you are a Windows 7 user, then you’ll be a bit surprised that you can’t run the game now despite being able to during the beta. Now, keep in mind that Windows 7 isn’t actually supported, but you can still play it.

To do this, follow the steps below.

  • Head over to the following location
C:\Users\<USER>\AppData\Local\Back4Blood\Steam\Saved\Config\WindowsNoEditor\
  • Here, open the GameUserSettings.ini file using a text editor like Notepad or Notepad++
  • Here, find the following variable, and change the value to false, as shown below
bCASSharpening=False
  • Save the file, and exit out

  1. Why the hell would I deactivate my antivirus software??? Don’t tell me to get another antivirus when I have been using them for years and with no issues. This is lame.

    • Are you referring to Webroot? It’s not the antivirus’s fault, but the game has a conflict with it. Multiple users have confirmed that disabling/uninstalling it fixed the issue for them.

  2. Sadly the code line fix doesn’t work if you got the game via gamepass on PC, the file structure for the WindowsApps is just so different even once you locate the correct folder for the game.
