  • Click on your 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 updates pending, the display screen will show you the option to Update Windows.

Allow D4 on Windows Defender Firewall

Your Windows Defender Firewall settings might be blocking the game and this might cause Diablo IV Crashing and Client Lockups. Here’s how you can add it to the Exception list:

  • Open the Firewall & Network Protection from your Windows Security.
  • Locate and click Allow an app through Firewall.
  • Look for the Diablo IV files in the list.

Repair Diablo 4 Files

It is quite possible that your Diablo IV files have a corrupted file in the midst or might have faced problems while downloading. Repairing your downloaded files will help you quickly fix the error you have been facing:

  • Open your Battle.net desktop application and then click the Diablo IV icon.
  • Now, look for the cogwheel-like Settings icon and then select the Check For Update option to make sure your game is updated.
  • If the game is up to date, select the Settings icon again and then select Scan & Repair.
  • Once you hit Begin Scan, the repairing will start and you might get rid of the Diablo IV Crashing and Client Lockups error.

Check if your Hardware is Overheating

Overheating components in your PC can cause lag, crashes and performance issues. You can keep an eye on your computer’s heating by downloading HWmonitor. This has been recommended by Blizzard itself and is safe to use.

  • Start HWMonitor and run it while you are playing the game until you face a crash or lag.
  • Check the max temps you see in the software. If you see that your CPU is going above 60 degrees celsius, or your GPU is going over 80 degrees celsius, that’s the problem causing Diablo 4 crashes.
  • Now that you’ve detected that overheating is the problem, you need to set the components to default speeds to ensure that the PC is not overclocking.
  • Make sure to clean the PC because collected dust can cause these heating issues.
  • Place your laptop on a hard surface instead of placing it on a soft surface which can cause heating.
  • Lastly, make sure the room you are in isn’t too hot – a temp of 27 degrees celsius or lower is preferred.

Additionally, you need to close all other applications while you are trying to launch Diablo IV to ensure a smooth gameplay session. Although uninstalling and reinstalling the game is a last resort, it is an option you can explore if all of these fail. However, we recommend you contact Blizzard Support first since they will provide you with professional help and they will benefit from these errors when the full version of the is game released.

That’s everything you can do if Diablo 4 keeps crashing on your PC. While you are here, make sure you check out Guides for more such fixes and other content right here at Gamer Tweak.
