Steam Cannot Launch

Help
1

I was having NVIDIA driver issues on Steam flatpak so decided to try Steam from nixpkgs. However I was getting bwrap: Can't bind mount /oldroot/exports on /newroot/exports: Unable to mount source on destination: No such device. So I did a fresh install thinking residuals from the Steam flatpak install was messing with bwrap but nope, I get the exact same error. I honestly don’t even know where to begin troubleshooting, it seems like I’m the only person in the world having this issue specifically with NixOS and nixpkgs Steam. Best I can tell it may be a permissions issue somewhere?

What’s mounted at /exports?

Please paste the content of /proc/mounts (minus data you consider private).

I had a similar symptom, although with /oldroot/v which was defined as

{
  fileSystems."/v" = {
    device = "//${nixcentre}/v";
    fsType = "cifs";
    options = [
      "username=guest"
      "uid=chrism"
      "gid=users"
      "x-systemd.automount"
      "noauto"
    ];
  };
}

I had to disable that mount and reboot.
