If you encounter a bug, proceed to https://bugs.kde.org/, check whether it has been reported.

Developers do not look for reports on social media, so they will not see it and all it does is clutter up the feed.
KDE can focus apps with a key-bind natively - in the Window Rules settings (even easier if you open the context menu on a window and go to More Actions > Configure Special Application Settings...). So I have Meta+Enter mapped to focus a terminal etc.
I don't know of a simple way to both open and focus with the same key-bind. KDE doesn't seem to have implemented ext-foreign-toplevel-list so I don't think external window management tools can do this yet.
System settings > Window management > Window rules: Set rules for a specific window (stuff like steam is tricky but works too) + "Add property" : add shortcut
Systemsettings > Windows management > kwin-scripts > get New modules. Look for krohnkite, polarium etc. Maybe there is something you looking for.
If you install krohnkite or something like that you have to search for the respective entries under systemsettings > keyboard > hotkeys > kwin and assign hotkeys to them
Krohnkite! 🥁
