4] Run the game in administrator mode

The next thing you can try is running the game in administrator mode. Sometimes, not having administrative privileges can be the major reason for the issue. So, grant administrative rights and check if it’s still a problem. Here’s how it’s done.

Right-click on the game exe file and choose the Properties option.
Click on the Compatibility tab.
Checkmark the Run the program as an administrator option.
Click on Apply > OK.

Now launch the game and check if you are still facing the problem.

It’ll open the DirectX Diagnostic Tool. Check the installed DirectX version on your system.
