Windows 11 language switch hot keys don't always work or work slowly.

2025-late-april, this bug still here, same as OP described better than I can.
All of my win11 machines exhibit this bug. My remaining win10 machines - as with all prior win-OS - do not exhibit this bug.
Basically, keyboard-switching has been broken to be unusable for people who actually need/rely on it (hint: everybody outside US).
There may be several bugs.
(1) on my machines, the UI for this appears to "animate", the same way slow web apps are wont to do.
Which makes no sense, for a user interface interaction which must be INSTANT. I am trying to 10+ characters per second. I do not need a multi-second "movie" event while I am typing??
(2) it feels like the bug has some sort of "getFocus/leaveFocus" issue, where the keyboard-switching maybe is tied to some sort of "select confirmation", so it is not enough to navigate down to the intended keyboard-option in the select list, the selection must sort-of-be 'confirmed'? possibly by some sort of focus-ended-event? I am not sure, but it feels like it, as I can see the intended language being HIGHLIGHTED/SELECTED, but my key presses continue to type the previous other keyboard layout, suggesting that the displayed/highlighted item is not 'confirmed'..?
(3) another way to describe my suspicion: It appears as though the actual switch EFFECT is not tied to the typed-"SWITCH-NOW" key command, but instead somehow tied to that the (secondary) UI part is "updated to reflect it". Which is insane - switching of keyboard layout should be INSTANT.

I wonder if the guys at microsoft (*) understand the usecase here:
It's not like people in europe wake up on a wednesday and think "You know, today, I think I will switch to ITALIAN keyboard layout, maybe around noon..?" 
  We don't switch keyboard layout once per day, we switch multiple times per minute, as we e.g. switch back and forth between US layout for coding, and european layouts for any text we need to write.

(*) The product managers, the product owners, whatever else MS throws at this.

So far, what I can see is that across a YEAR - 12 months - nobody at 'the biggest software company in the world' has cared to address this?

Hello? Anyone at microsoft still using keyboards? Can you look into this at some point? Maybe allow me to code it for you?
At this point, I'm considering coding my own "switch keyboard layout" app for windows, there has been a market for such an app for 12 months now..?
