Also, I'm running Fedora on VMware 16.

Sorry, I'm stupid. I have manually enabled v1 cgroups to use Docker as stated in this post.

Got the same error on Fedora 34, I don't think i am on the old cgroups, any hints?

Update:

sudo grubby --update-kernel=ALL --args="systemd.unified_cgroup_hierarchy=1" helped,
despite cat /etc/default/grub not showing systemd.unified_cgroup_hierarchy=0 before.`
