Update graphics adapter driver
Edit the game MXML file
Reinstall the game

Let’s take a look at the description of the process involved concerning each of the listed solutions.

Before you proceed with the solutions below, we suggest you first restart your PC. After your computer reboots, open Steam, log in your user account and launch the game triggering the error and see if the error reoccurs. Also, make sure the OpenGL and OpenCL Compatibility Pack is installed on your Windows 11/10 gaming rig and try launching the game. In addition, we suggest you check for updates and install any available bits on your gaming device and see if the error occurs when you launch the game. On the other hand, if the error started after a recent Windows update, you can perform System Restore or uninstall the update – but if you prefer not to do neither, you can then go ahead with the solutions below.

1] Update graphics adapter driver

The Unable to initialize OpenGL error on your Windows 11/10 gaming PC is graphics driver-related. So, you can begin troubleshooting to fix the issue by updating the graphics card driver on your system.

Below are your options;

You can manually update the graphics driver via Device Manager if you have already downloaded the .inf or .sys file for the driver.
You can also update the driver via Command Prompt.
In Windows Update, you can as well get the driver updates on the Optional Updates section.

If updating the graphics card driver didn’t fix the error, as suggested on the error prompt, you can reinstall the graphics adapter driver. To perform this task, you first need to uninstall the graphics card driver using Display Driver Uninstaller (DDU), and then download the latest version of the driver from the official website or other reliable sources and install it on your PC.

2] Edit the game MXML file

MXML is an XML-based user interface markup language first introduced by Macromedia in March 2004. Application developers use MXML in combination with ActionScript to develop rich web applications, with products such as Apache Flex. Files with the MXML extension are associated with Adobe Flex technology. The MXML file contains the source code in an XML-based markup language and can be used to declaratively define nonvisual aspects of an application, such as access to server-side data sources and data bindings between user-interface components and data sources.

This solution requires you to edit the problematic game MXML file. Here’s how:

Launch Steam client.
Right-click the problematic game.
Select Properties.
Go to LOCAL FILES and click BROWSE LOCAL FILES.
Next, go into Binaries > Settings.
Open the MXML file.
Now, change FullScreen property value from true to false.
Next, check your screen resolution settings, then change the ResolutionWidth and ResolutionHeight property value accordingly.
Save and exit the MXML file when done.

Relaunch the game and see if the error in focus reoccurs. If so, try the next solution.

3] Reinstall the game

If neither of the solutions above wasn’t helpful, as a last resort you can uninstall the problematic game, reboot PC, and then download and reinstall the latest version of the game on your gaming device.

Any of these solutions should work for you!
