A long persisting bug in the Fortnite community, ‘Error Code 91‘ has been the source of many frustrating crash stories. As of now the bug is still present and Epic Games has yet to release an update that fully solves the issue.
Error code 91 occurs most often when a player attempts to join or invite someone to a party, the game then crashes and player is presented with ‘error code 91’. Shutting down your device and restarting sadly does not solve the issue.
The error occurs across all platforms whether you are using a PC or any console and has been around for years. From what I’ve gathered it seems to be a client error that could involve corrupted game files.
Solution 1: Authenticate Game files
The first attempt you should make is to authenticate your Fortnite game files, this can be done by:
- Restart your device to ensure no other program interferes with the verification
- Open Epic Games client
- Navigate to the Fortnite tab,
- Press the ‘…’ icon next to the game in your library
- Select the Verify option in the dropdown list
- Wait for the verification process to end (It may take up to 10 minutes)
- Test the game by launching and if the error persists try one more restart
Solution 2: Reinstall Fortnite
As frustrating as it may be, reinstalling has often solved client related issues for gamers and this issue is no different:
- First uninstall all files and related components then restart your device
- Download the latest version from the Epic Games launcher
- Install the game as normal
If these solutions did help you fix the issue then be sure to also safely shutdown your device and avoid sudden shutdowns while Fortnite is running, this also potentially helps prevent other game files from becoming corrupted.
Make sure your party members also verify their game files so the error doesn’t transfer over to you. Let’s hope Epic Games finds a solution for error code 91.
