System: docker-ce version 20.10.6 on Debian buster 10.9

Bug: After last update of conainerd.io from version 1.4.4-1 to 1.4.6-1 docker container immediately stop working.

Error messages from docker status:

cleanup: failed to delete container from containerd: no such container
failed to start container ... task 64c... already exists: unk

Restarting docker did not solved the problem.

Workaround: Downgrade containerd.io to previous version (sudo apt-get install containerd.io:amd64=1.4.4-1) and container immediately worked again.
