Update your GPU drivers

GPU drivers are one of the main components of PC gaming and need to be kept up to date. If your GPU is not up to date, you will most likely experience the Diablo IV Crashing and Client Lockups error. To fix this, simply go to your GPU driver website to check for and download updates. Nvidia users can click here and AMD users can follow this link.

Update Microsoft Windows

Make sure your Windows is up to date and that you haven’t missed any new updates. Since this can lead to an error, you will need to follow these steps:

• Click on the Start menu and then click on Settings.
• In the new window, you need to look for Update and security.
• Now to update windows, click on the button that says “Check for Updates”.
• If there are pending updates, the display screen will show the Update Windows option.

Allow Diablo IV in Windows Defender Firewall

Windows Defender Firewall settings can block the game, which can cause Diablo IV to crash and the client to freeze. Here is how you can add it to the exclusion list:

• Open Firewall and Network Protection under Windows Security.
• Find and click Allow an app through firewall.
• Find the Diablo IV files in the list.
• If you can’t find it, follow these steps:
  • Click Change Settings.
  • Click “Add another app”.
  • Locate the Diablo IV files and then add the game to the exclusion list.
• Once you add the game to the exclusion list, it should have no issues with Windows Defender.

Restore Diablo IV Files

It’s possible that you have a corrupted file among your Diablo IV files, or that you’re having trouble downloading. Restoring downloaded files will help you quickly fix the error you are facing:

• Open the Battle.net desktop app and click on the Diablo IV icon.
• Now look for the gear-shaped settings icon and then select the “Check for Updates”option to make sure your game is up to date.
• If the game is up to date, select the “Settings”icon again and then select “Scan and Repair”.
• As soon as you click “Start Scan”, the repair will begin and you can get rid of the Diablo IV Crashing and Client Lockups error.

Also, you need to close all other applications while you are trying to launch Diablo IV to ensure a smooth gaming experience. While uninstalling and reinstalling the game is a last resort, it’s an option you can look into if all of that doesn’t work. However, we recommend that you contact Blizzard Support first, as they will provide you with professional assistance and will be able to benefit from these bugs when the full game is released.
