Fortnite critical errors can be a major hindrance to your gaming experience, especially if they cause the game to crash or fail to launch. The error, accompanied by the message “A critical error has occurred, we’re so sorry to hear this,” can be caused by a variety of reasons, including issues with drivers, anti-cheat, system settings, and more. In this guide, we’ll cover a few methods to help you fix this issue and get back into the game.
How to fix A critical error has occurred We are very sorry this happened in Fortnite
The first step in fixing the problem is updating your graphics card drivers. Make sure you download the latest drivers from the official websites of manufacturers such as AMD and Nvidia. This can significantly improve the stability of the game.
The next step is to check and restore the BattlEye anti-cheat system. Sometimes launch problems may be related to it. To do this, go to the game folder, find the BattleEye folder and run the Uninstall_BattlEye.bat and Install_BattlEye.bat files one by one, then reboot your computer.
If the problem persists, try changing the TDR (Timeout Detection and Recovery) settings in the registry. This may help if the error is related to a slow response from the video card. To do this, open the registry editor, go to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\GraphicsDrivers and set the TdrLevel parameter to 0.
You can also try changing the game’s configuration file. Open the configuration file in the AppData\Local\FortniteGame\Saved\Config\WindowsClient folder, find the line bPreferD3D12InGame and set its value to “False”. After that, save the file and set the “Read Only” attribute for it.
If none of these methods helped, try disabling fullscreen optimization and setting the game to compatibility mode. To do this, open the game file properties, go to the “Compatibility” tab and activate the appropriate options.
Finally, make sure all the game files are in order by verifying them through the Epic Games Launcher. In the Library tab, click the three dots next to the game and select Verify.
