Getting GPU passthrough to work on WSL2 for windows 10

My Ubuntu install is not picking up my CUDA card. I have an GTX A5000. I ran through the following steps in section 4.2.6 from this tutorial:

wget https://developer.download.nvidia.com/compute/cuda/repos/wsl-ubuntu/x86_64/cuda-wsl-ubuntu.pinsudo mv cuda-wsl-ubuntu.pin /etc/apt/preferences.d/cuda-repository-pin-600wget https://developer.download.nvidia.com/compute/cuda/11.4.0/local_installers/cuda-repo-wsl-ubuntu-11-4-local_11.4.0-1_amd64.debsudo dpkg -i cuda-repo-wsl-ubuntu-11-4-local_11.4.0-1_amd64.debsudo apt-key add /var/cuda-repo-wsl-ubuntu-11-4-local/7fa2af80.pubsudo apt-get updatesudo apt-get -y install cuda

However when I try to build a sample as instructed in section 4.2.7 I get the following error:

[./BlackScholes] - Starting...CUDA error at ../../common/inc/helper_cuda.h:779 code=100(cudaErrorNoDevice) "cudaGetDeviceCount(&device_count)"

so WSL is not picking up my GPU. The current version of the driver I am running is 30.0.14.7239

When I run uname -r I get the following:

5.10.102.1-microsoft-standard-WSL2

edit:Version of windows I am running is windows 10(OS Build 19042.1586). I opted to be in the "windows insiders" group, but I don't think this is the latest build.
