Some people while trying to install Back 4 Blood via Gamepass on PC keep getting an error that prevents them from installing the game. To fix this error, you should try to reinstall the Gaming Services App on your PC.

Press Enter and install the app on that page. Here you have to select the “yes” option when you see a prompt.

Once done now restart your computer and try and install Back 4 Blood again.

Crashing on Startup

Some people complain that the game crashes after they get the Epilepsy Warning. If you are also facing the same problem, the following steps can be used.

Try verifying the Integrity of your Game Files, to check for any possible corrupted files. To do so, go to your library in Steam Client. Right-click on the game and enter Properties. Here, select Local Files and Verify the integrity of game files.

If this doesn’t resolve the issue, make sure your GPU drivers and Windows(or any OS you are using) are up to date. If not, check for new updates and download and install if you find any pending ones.

For a third option, you can move the game files to the same storage drive in which you have installed your Steam Client.

Some players also reported that having the Epic Games client opened might get the game working. You can try the same and see how things go.

Error Finding Players

Few players have reported that they are having issues finding players to play Co-op with. For this, Make sure your internet connection is good and working. It’s preferred if you use a wire connection.

Make sure your NAT Type is Open and has optimal settings so you can easily join and invite other players.

Another reason for this is that most players select the Continue Run option at the menu. When this is selected, the game resumes from a random point you left it on and tends to find players who also started at this spot, making it harder to find players.

Simply select Quick Run or New Run to start new sessions, as this will allow you to easily find new players to play with.

The Continue Run option is more suited to players who are playing with their friends and want to hold off any session to complete with their friends later on.
