Description of problem: Try to choose Breeze-Dark theme from System Settings that was available in M7 and it can't be installed, settings says its not present, though its visible. The problem seems to be a missing file 'window-decorations.css' which is present in '/usr/share/themes/Breeze' but not in '/usr/share/themes/Breeze-Dark', see MCC screenshot. Machine was upgraded by CLI following the release notes guidance. Copied 'windows-decorations.css' over to '/usr/share/themes/Breeze-Dark' and the theme becam selectable/installable in System Settings afterwards but I've no way of telling if the CSS is relevant for this theme.

Thank you for this report, your diagnosis, and the useful screenshot. /usr/share/themes/Breeze-Dark/ exists, but does not have the window_decorations.css file indicated which exists in /usr/share/themes/Breeze/ Assigning this to the KDE team.

See also https://bugs.mageia.org/show_bug.cgi?id=28299 Seems a duplicate about missing window_decorations.css complains with GTK app. Normally, now, GTK apps should be set to "Breeze" theme in GTK/GNOME appearance settings in systemsettings5, AND Dark version comes from selecting it for QT/Plasma variant. Normally, as soon as you select Dark Breeze for Plasma/QT apps, it should be activated for GTK/GNOME apps, automatically, modulo a restart of the GTK apps. BUT: root applications like rpmdrake and MCC will still display Light version of Adwaita theme. (because they run as root).
