Back 4 Blood Crashing on Startup Fixes

Steam Version Crashing Fix

Those who own Back 4 Blood via the Windows store seem to have more issues, but Steam players are also getting crashing on startup.

Reddit user Cyndershade has found a bypass to the Steam version crash, which helped a lot of people in the same situation:

  1. Download and install Epic Games app from the official webpage
  2. Make sure that its updated to the latest version
  3. Launch Steam app
  4. Start Back 4 Blood, while Epic Games app stays open in the background

This may sound like a weird solution, but it did work for many Steam users. It appears that Epic Games app fixes the anti-cheat bug that is persistent during the startup of Back 4 Blood.

Sharpening Error Fix

Some players report that Back 4 Blood launches in borderless windowed mode and then crashes at startup. This is caused by the Sharpening setting in the configuration file, which can be fixed using these steps:

  1. Go to "C:\Users\[USERNAME]\AppData\Local\Back4Blood\Steam\Saved\Config\WindowsNoEditor\" folder on your PC
  2. Right-click on the "GameUserSettings.ini" file
  3. Open the file with Notepad
  4. Press F3 to search for "bCASSharpening=True" line in the text
  5. Change it to "bCASSharpening=False"
  6. Save and exit

When you try to launch Back 4 Blood, it should start without crashing and then you can set it to open in full screen mode through graphics settings.

Adjust Post Processing Quality

If you can launch the game, but it crashes soon after launch or during gameplay, then there is a possible fix that may eliminate these crashes:

  1. Start Back 4 Blood
  2. Go to the game's "Options" menu
  3. Select "Graphics" options
  4. Set "Post Processing Quality" to "Low"

This simple action may also solve a few other issues with the game's graphics.

Unreal Engine 4 Crash Fix

Some players experience crashing at startup with the following error message: "The UE4-Gobi Game has crashed and will close".

This bug is connected with the Unreal Engine 4 and the DirectX processing. You can solve this issue by trying the following method:

  1. Start Back 4 Blood
  2. Go to the game's "Options" menu
  3. Select "Graphics" options
  4. Set "Graphics API" to "DirectX 11" or "DirectX 12"

If your default setting was DirectX 12, and your game crashed, then you need to switch it back to DirectX 11, and vice versa.

Fatal Error Fix

B4B players that receive the "fatal error line 872" and "rendering thread exception fatal error line 258 error" message can try the following fix:

  • Go to "C:\Users\[USERNAME]\AppData\Local\Back4Blood\Steam\Saved\Config\WindowsNoEditor\" folder on your PC
  • Right-click on the "GameUserSettings.ini" file
