What is the issue?

now i know there has been a lot other issues about this problem and most of them has been solved but i have not found an answer for my specific scenario, most of the cases has been on linux.
In other threads i seen people say its because they don't have enough vram that it automatically uses the cpu, but i have 24gb vram so I don't think that is the case

now when i run "nvidia-smi" it returns:

Cuda compilation tools, release 11.8, V11.8.89
Build cuda_11.8.r11.8/compiler.31833905_0

thanks for the fast response! I couldn't find any apparent reason why it might not be working with mu gpu in the logs.
i did find this which i thought was interesting
level=INFO source=types.go:123 msg="inference compute" id=GPU-870535b8-d8b2-fcf2-c0fc-f4ce5c9136c2 library=cuda variant=v12 compute=8.9 driver=12.4 name="NVIDIA GeForce RTX 4090" total="24.0 GiB" available="22.5 GiB"
which means my gpu is being detected and cuda is working
