Version 1.2.0 is unsupported

Problem/Motivation

When I install version 1.2.0 on Drupal 10.4.3, I have the alert "Your currently installed release is now unsupported, is no longer available for download and no update is available. Uninstalling everything included in this release is strongly recommended!", do you know what is the problem ?
Thanks
