Why is my wired USB keyboard not working properly anymore after standby?

Question

My system…

1. Keyboard: HP Premium USB (cable)
2. OS: Windows 11
3. Port: USB 2

How to reproduce…

1. Enter Windows standby mode
2. Resume Windows
3. In the first few minutes, the keyboard still works fine
4. However, after a few minutes, the special characters (¦, @, #, ...) that need the ALT Cntrl key stop working

What I have tried…

• Unpluging the keyboard USB cable and reconnect it (issue persists)
• Restarting Windows "solves" the issue
• Disabling selective USB suspension mode (issue persists)
• Restarting USB device (issue persists)

Current solution…

I managed to set up an AutoHotkey script, that solves this issue for the most used characters in most scenarios, but there are input fields where AHK does not work either:

<^>!2::Send {ASC 64} ; @
<^>!3::Send {ASC 35} ; #

Is there a better way to solve this issue?

I first thought it was due to my old PC and/or Windows 10. But now, since I just got a brand new PC with Windows 11, the issue still persists.

Windows Support couldn't solve the issue.
