nerdctl run `no such file or directory` when running inside a pod

Question

I have a Pod

apiVersion: v1
kind: Pod
metadata:
  labels:
    app: ...
  name: ...
spec:
  containers:
    - name: ...
      image: ...
      securityContext:
        privileged: true
        runAsUser: 0
      volumeMounts:
        - mountPath: /var/run/containerd
          name: containerd-dir
        - mountPath: /var/run/containerd/containerd.sock
          name: containerd
  restartPolicy: Always
  volumes:
    - name: containerd
      hostPath:
        path: /var/run/k3s/containerd/containerd.sock
    - name: containerd-dir
      hostPath:
        path: /var/run/containerd

which mounts the containerd.sock. Inside the pod, I have nerdctl installed (RUN /home/linuxbrew/.linuxbrew/bin/brew install nerdctl)

I'm able to run nerdctl ps successfully, and it returns a list of the running contains (that I ran from the host) - but when I try to run nerdctl run, for example nerdctl run -d redis, I get the error message

FATA[0000] no such file or directory

Running nerdctl --debug-full run -d redis doesn't reveal anything

/# nerdctl --debug-full run redis
DEBU[0000] verification process skipped                 
FATA[0000] no such file or directory

nerdctl run works fine when I run it on the host (targets the same containerd.sock) and inside the pod when I run nerdctl ps, I see the containers that I launched succeessfully on the host.

nerdctl pull works fine from within the pod

Any ideas?
