On Mac, I'm running Lando inside Docker. I'm on Lando v3.0.1 and was running Docker Desktop v2.2.0.5 successfully.
Docker released stable an update v.2.3.0.3 and I installed it. After that I attempted to run Lando, but got a warning message stating the Docker Desktop version is not supported.
So, I'm wondering if it is possible to roll back to my previous Docker Desktop version without uninstalling Docker.
All your previous containers should still be there.
If you're using Docker Desktop, I found deselecting the option Use Docker Compose V2 fixed my problems. Spent a long time working on reinstalling things. Definitely worth a try before doing anything big.
So, I run the installer of the previous Docker Desktop version: 2.2.0.5 - got a warning message stating that a newer Docker already exists and if I wanted to replace it (stop, or keep it both). I selected 'Replace'. The installation went successful. But when I open Docker all my running containers were gone. I run lando to recreate my Drupal 7 site. I got the "Boomshakala" from lando confirming that the app has started up correctly, and provided with its corresponding vitals -including the APPSERVER URLS. But when I access the URL, I got an error message: "Error: the website encounter an unexpected error. Please try again later." The uncaught exception thrown in shutdown function: "PDOException: SQLSTATE[]: Base table or view not found:1146 Table 'drupal7.semaphore' doesn't exist...."
To solve this, I imported and old copy of the drupal database site: lando db-import .sql
then I navigated to the docroot folder, and run a database update: lando drush upddatedb
All good now; thanks @halfer for your comments!

As said @patricknelson
Sadly, this no longer works. Now it only says "Existing installation is up to date".
And workaround of Docker Descktop downgrade with retains of the data described below:
Get a list of containers
docker container ls
Commit the container to save the data:
docker commit -p 64bf7c9f7122 new-image
where 64bf7c9f7122 - id of my container
new-image - new image name
Save the committed image with changes to the archive
docker save -o c:\backup.tar new-image
Delete current Docker Desktop
Install desired Docker Desktop version
Unpacking the image in docker
docker load -i c:\backup.tar
run container
docker run --name sample-container new-image
Congrats, all data saved and Docker downgraded
The quick hack here for Lando specifically, is just to reinstall Lando from the installer for the version you want. We've bundled the supported version of Docker Desktop with Lando itself which means you can always specifically install the supported version when installing Lando. This may wipe out your containers and volumes, so be careful!
