System Rebuild is typically what you want for docker errors. It will rebuild all the docker containers (while preserving your data). Sounds like that didn’t work though?
Did you recently do an update from an old version? If so, do you know what version? We’d like to reproduce this error if possible - there might be a bug in a migration.
If none of that works, probably the best approach is to reflash the OS to a fresh copy of the latest for which you can find instructions here (assuming your Vaio has an Intel or AMD cpu):

But if the last thing you did was an upgrade to get to this state, please let us know as it might require more care than simply flashing the latest and picking Recover > Use existing drive.
