Permission denied: unknown with docker on Fedora 34

Today, after update Fedora 34, docker no longer run and show the following error:

docker run -it --rm alpine /bin/sh
docker: Error response from daemon: OCI runtime create failed: container_linux.go:380: starting container process caused: process_linux.go:545: container init caused: process_linux.go:508: setting cgroup config for procHooks process caused: cannot fetch program from id: get program by id: permission denied: unknown.

The same error occur when running docker with sudo. I try to uninstall docker removing all files withou results.
So, changing the permissions of docker.socket take the same effect:

sudo chmod 666 /var/run/docker.sock

The error persist.

Thanks for help.

Hello, I had the same issue, I found a solution here : https://www.reddit.com/r/Fedora/comments/onui0l/docker_not_working_after_latest_update/

Basically, you need to downgrade containerd.io back to version 1.4.8 ( sudo dnf downgrade containerd.io)
