Could you please tell me your video driver version? You can use the following command and tell me what is the output:
glxinfo | grep version
You may need to install mesa-utils package in order to do this:
apt install mesa-utils
At this point, I would suggest you update video drivers to the 495 version from Nvidia's official site

Or you can use the latest 510 version from this link

Please, let me know if this helps
