I tested by first installing WSL "wsl --install" then I followed the instructions to install Podman on Windows. I was able to start the Podman machine. I then had my VM auto-shutdown, waited 30 minutes. After starting my VM I can still run the Podman commands.
Maybe there is some policy or something on the OS that is resetting this configuration for you? Can you try to reinstall using the method I followed?
