Ran into a similar problem in my setup.

If you look at the NIX_CONFIG it includes spaces: "\'NIX_CONFIG=extra-experimental-features" "=" "nix-command" "flakes\'". Feels to me this should be a single VARG, but got broken down into several arguments. If I clean NIX_CONFIG the command works.
Checking my flakes, I can see:
default = pkgs.mkShell {
NIX_CONFIG = "extra-experimental-features = nix-command flakes";
I think this is just used when bootstrapping the config. However it this format works with the other command.
