The last version 21.23

I also have read this, but I have not expected to break all with this update. We have updated dozens of VM's from Debian12 to 13 and nothing was broken. But OK, I will reinstall a Debian Bookworm and restore a backup now

As stated above, after upgrading our VM with kaspersky Security Center 15 to Debian13 I cannot login on the management console: Has anybody the same experience and maybe a solution for this problem? Thanks in Advance
