Using the device manager, go to display adapters, right-click on your graphics card, and select "Update driver." You can also manually download the latest driver from your graphics card manufacturer's website. Once the drivers are updated, restart your computer and try launching the application. In some cases, a conflict with another program or a system setting might cause the error. To identify this, you can perform a clean boot. A clean boot starts Windows with a minimal set of drivers and startup programs. This is helpful to eliminate software conflicts. To do a clean boot, press the Windows key + R, type msconfig, and press Enter. In the system configuration window, go to the "Services" tab and check "Hide all Microsoft services," then click "Disable all." Next, go to the "Startup" tab and click "Open Task Manager." In the Task Manager, disable all startup items. Then, restart your computer. If the error is gone after the clean boot, you can re-enable the programs one by one to determine which one is causing the conflict. These advanced troubleshooting steps can be more effective in resolving the error. Remember to proceed cautiously, especially when downloading and installing files from the internet, and always ensure that your system is backed up.
