If it turns out that this issue is being caused by a specific version of your NVIDIA GPU’s driver that your computer has, the easiest way to fix it should be to update the GPU’s driver software to the latest version. Use the following steps to do so:

Step 1: Navigate to the NVIDIA GeForce website using a browser.
