Hi, have you solved it?

[eehoeskrap]

Hi. In my case, the problem was caused by the A100 GPU not supporting WDDM. This was resolved by running it on an RTX series GPU.

Hi. In my case, the problem was caused by the A100 GPU not supporting WDDM. This was resolved by running it on an RTX series GPU. My gpu is 1080Ti, but this problem still occurs. I don’t know if it is a problem with the Nvidia driver version.
