Some keystrokes dont get recognized in vm [Windows-Host]

[Nickmato]

## Setup I am running a Windows 11 64-bit host, with virtualbox 6.1.32 64bit. The host is running headless with windows remote desktop access to it.

## How to recreate

1. connect to the windows host via rdp
2. check that keyboard and mouse are working. (i.e. against a browser writing this issue)
3. install virtualbox
4. create a vm (in my case linux)
5. start the vm
6. try to input text into the vm (tried with captured pointer and without)

## What happens

When pressing any key from ("a",...,"z","1",...,"0") no press seems to be registered by the vm. Pressing enter or backspace the vm seems to register the key being pressed.

## What should happen

"Any" keypress except the "hostkey" should be send to the vm.

## What kinda worked as a workaround

All displayable chars as keypresses from the "onscreen keyboard" seem to be recognized and send to the vm. But it is a pain in the bum.

I would love to hear back, help where i can, would love to recieve feedback and a fix would be aweasome.
