Also, can you please run "C:\Program Files\NVIDIA Corporation\NVSMI\nvidia-smi.exe" ? what is printed out

i could not run the nvml-smi exe. But i fixed the error by replacing the nvml.dll (2017) file in the C:\Program Files\NVIDIA Corporation\NVSMI with  the C:\Windows\System32 nvml.dll (2020) file. And now i can render with my gpu. thank you for the help guys

Not an AutoDesk user, but was using a software library called py3nvml (for accessing GPU stats using a programming language called python) and I did the same thing.

It worked!
