I have problem dependencies with my DEBIAN 12.
I tried to install DEBIAN 13, cancel the download, try to return to DEBIAN

Update the packages and full upgrade the system
Try fix packages with the following command:
sudo apt --fix-broken install
But the system crashed.
What can I make?
Did you back up and/or archive your data before attempting the major
upgrade? If the answer is "no", then I suggest that you boot a live
Linux distribution, and back up and/or archive the contents of all of
your disks immediately.
Did you take an image of the operating system (OS) disk before
attempting the major upgrade? If so, restore the OS disk image.
If you did not take an image of the OS disk before attempting the major
upgrade, then you have two basic choices:
1. Find the problem(s) and fix them.
2. Do a fresh install onto another disk and recover configuration
settings and/or data from the crashed disk.
In the past, I tried #1. It required a lot of knowledge, a lot of
effort, and a lot of time. I never knew if I was going to succeed, or
how long it would take. Even when it appeared that the problem(s) were
fixed, I often encountered problems later that I had missed.
My strategy with FOSS OS's is to start with a known good state (fresh
install) and always move forward to the next known good state --
installing packages, updating/ upgrading the OS, configuring the OS and
packages, etc.. If a move produces a bad state, I revert to the
previous known good state. To do so, I keep good records, check in OS
configuration files I touch into a version control system, take backups
regularly and as needed, create archives regularly and as needed, and
take images of the OS disk regularly and as needed.
