Bullseye (and bullseye-backports) does not have xserver-xorg-core 2:21.1.4-1 [1].
Have you both bullseye and testing/sid in your sources.list and/or packages installed
from testing/unstable additionally to stable / stable-backports?

xserver-xorg-video-nvidia on backports [2] specifies the dependency on xserver-xorg-coreas
you see it.
The solver cannot fulfil it, at is seems a newer one is already installed or about to be
insalled. So seems that there is at least one package requiring a higher version installed… 
This would be another indication that there was some mixture of suites… 

[1] in a bullseye with backports chroot:
root at isildor:/# apt-cache policy xserver-xorg-core
xserver-xorg-core:
  Installed: (none)
  Candidate: 2:1.20.11-1+deb11u2
  Version table:
     2:1.20.11-1+deb11u2 500
        500 http://ftp.de.debian.org/debian bullseye/main amd64 Packages

[2] https://packages.debian.org/bullseye-backports/xserver-xorg-video-nvidia

If you still seeing the issue, please let us know any additional information you
might have… Marking as moreinfo therefore.
