error: cannot kill cgroup '"/sys/fs/cgroup/system.slice/nix-daemon.service/nix-build-uid-30002"'

Describe the bug

I interrupted a deploy-rs command. I had nix builds in background overheating my CPU that I killed manually.

Then I tried to run another nix command (nixos-rebuild) and I get

...

I am not familiar with slices. I stopped the daemon and socket and started both again but I would still get the same error.

I tried to remove the folder to no avail

I would expect a daemon restart to fix this. I've found #11412 that looked related. Maybe it fixes my issue ? Now I guess I 'll just restart :s

nix-env --version output
nix (Nix) 2.24.10
