I used to switch between screens without mouse. It focused correct window on each screen. Now it seems to be broken as I don't see any effect. Though hotkey works, because there is error popup when option "Active screen follows mouse" is ON. Also "Window to Next Screen" works as expected.
Corresponding option is "Separate screen focus" whose presence is questionable. This option should be turned on and grayed out implicitly if there are screen switching keyboard shortcuts set.

If you close the last window on a screen, then focus won't be moved to another screen. I agree that "Next to switch screen" shortcut is broken without "Separate screen focus" option being on. Perhaps we need to add some enum parameter to FocusChain::getForActivation in order to control its granularity (per screen, or per desktop). "Separate screen focus" should still take precedence if it's on.
> then focus won't be moved to another screen I don't see a trouble with it. I see trouble when I press shortcut but it does nothing and doesn't give you a clue why it doesn't work.
With this option ON I didn't feel any anomalies for 7 years of experience. So acquiring focus on different screen without explicit user intent looks an artificial task to me.
This has been fixed with https://invent.kde.org/plasma/kwin/-/commit/354a71855e04ee28311410e1b6d2a69cddcbcdbc, the shortcut will always work in Plasma 6.1+, independently of the options
