[Koha] Error in Koha 22.05?

Hello, I would like to point out a bug in Koha after the update to 22.05. Koha is also included in the package management of Ubuntu 22.04 LTS and can be updated together with Ubuntu. I had skipped the short time preceding Koha update because of errors. However, the current update to 22.05 apparently also contains bugs: The structure of the borrowers table seems to have been changed compared to previous versions. Existing user data are not correctly loaded into the new structured table with the update, so that no login, e.g. as superlibrarian, is possible anymore. Possibly this phenomenon is caused by the skipped update to the previous version? Many greetings Eberhard Pietzsch
