I have Ubuntu 20.04 VM with installed latest docker_compose, after the last VM update and restart all the docker's data is missing.

I can't be sure, but is the data directory been changed due to the latest update? I paid attention that Docker Root Dir: now is /var/snap/docker/common/var-lib-docker - can't be sure what it was before...
$ sudo du -hs /var/snap/docker/common/var-lib-docker
644K /var/snap/docker/common/var-lib-docker
This directory almost empty (644K) rather than the old one (7.5G) /var/lib/docker/ directory

7.5G /var/lib/docker/
I tried to stop the docker service and replace the contents of /var/snap/docker/common/var-lib-docker/ with data from /var/lib/docker/ but the results are the same empty responses on docker ps -all and others
$ docker ps -a

I have this /hello image after docker_compose reinstall (Docker problems in Ubuntu 20.04), where all the others?

How to restore containers data to the previous state and get rid of this error: level=error msg="fatal task error" error="task: non-zero exit (1)" module=node/agent/taskmanager?
