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
sudo mv cuda-wsl-ubuntu.pin /etc/apt/preferences.d/cuda-repository-pin-600
wget
sudo dpkg -i cuda-repo-wsl-ubuntu-11-4-local_11.4.0-1_amd64.deb
sudo apt-key add /var/cuda-repo-wsl-ubuntu-11-4-local/7fa2af80.pub
sudo apt-get update
sudo 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.

Have it working now. After signing up for windows insiders group I had to go to windows update and go into optional updates. I added the 21H2 patch and everything seems to be happy now.
