I have a suspicion kind isn't going to work well on void due to the differences in how it does things compared to the other distros we test with.

Can you add the output from docker info?

docker: Error response from daemon: failed to create task for container: failed to create shim task: OCI runtime create failed: runc create failed: unable to start container process: error during container init: error mounting "cgroup" to rootfs at "/sys/fs/cgroup": mount cgroup:/sys/fs/cgroup/elogind (via /proc/self/fd/7), flags: 0xe, data: elogind: invalid argument: unknown.

This error means docker can't even create the container on this host, before any of our own code begins running inside the container.

The cgroup mount isn't even specified by kind, so

/remove-kind bug /kind support

I recommend using a different distro.

You can see the same issue affects other with a quick search of the error e.g. https://github.com/void-linux/void-packages/discussions/45921
