@Van Snyder
In reply to your private message, you need to install the two packages below:

user@host:~$ apt search libwebkit2gtk-4.0-37
Sorting... Done
Full Text Search... Done
libwebkit2gtk-4.0-37/stable,now 2.32.4-1~deb11u1 amd64 [installed]
  Web content engine library for GTK

libwebkit2gtk-4.0-37-gtk2/stable,now 2.32.4-1~deb11u1 all [installed]
  Transitional dummy package

user@host:~$ 

While, usually, 'stable' currently is a pointer to 'bullseye' and vice versa, this seems to be broken for 
'libwebkit2gtk-4.0-37'; therefore:

*** OLD /etc/apt/preferences ***

Package:        *
Pin:            release a=bullseye
Pin-Priority:   745

*** NEW /etc/apt/preferences ***

Package:        *
Pin:            release a=stable
Pin-Priority:   745

Package:        libwebkit2gtk-4.0-37
Pin:            release a=stable
Pin-Priority:   1005

The second block enforces the downgrade, you may comment it out afterwise.

Hope this helps, Christian

P.S. I am using GNOME, not KDE.
