If this does not work, Could you try to upgrade your Graphics Driver?
- Check the type of display adapters in the Device Manager. For example, here my display adapter type is Intel UHD Graphics 620.
- Then you can try to find the latest version of the graphic driver on Intel official website: https://www.intel.com
- Download and install the latest graphic driver.
