With Helldivers 2 launching, many players are encountering issues, such as the “Failed to Join” error. However, some players are experiencing an even more serious problem with the game’s anti-cheat software making the game unplayable. But fear not, we have a solution to fix the nProtect Anti-Cheat error in Helldivers 2 that could save you a lot of time.

Helldivers 2: How to Fix the nProtect Anti Cheat Error

The nProtect Anti-Cheat error appears to be caused by some players’ anti-virus software blocking the game’s anti-cheat software. Fortunately, there’s a simple fix that you can try yourself.

Follow the steps below to resolve the nProtect Anti-Cheat error:

• Look for the Helldivers 2 game folder within File Explorer.
• Locate the GameGuard folder within the game folder, then delete it.
• Open Helldivers 2 from the File Explorer, and a new GameGuard folder should be created.
• Depending on your anti-virus program, whitelist GameGuard as an allowed app.

For example, if you’re using Windows’ native anti-virus program, you can whitelist the game itself. The process may vary based on the specific anti-virus program you are using.

After completing the steps above, be sure to restart your computer. Once you’ve done that, Helldivers 2 should work as intended. However, if the method described does not resolve the issue, you may need to wait for a fix from Arrowhead Games. In such cases, your best option may be to wait for an official update.
