Screenshots

VIA Version

• I am using https://usevia.app/
• I am using the latest release of the desktop app from https://github.com/the-via/releases/releases/latest

Keyboard firmware VIA protocol
12

Desktop (please complete the following information):

• OS: Windows 11 23H2 22631.3296
• Browser Google Chrome 124.0.6367.8

Custom json definition?

• I am loading a custom json definition using the designer tab

Sanity checks

• I have tried connecting the keyboard directly to the computer (i.e. not using a USB hub)
• [] I have flashed the latest firmware from https://www.caniusevia.com/docs/download_firmware
  No firmware at https://www.caniusevia.com/docs/download_firmware exists for this keyboard because manufacturer has not provided it there.

Additional context
On Linux VM to which I passed through the USB device/KB I was able to configure the keyboard perfectly.
Tried re-flashing the newest KB FW provided by manufacturer. No change after a re-flash. https://www.keychron.com/pages/how-to-factory-reset-or-flash-your-qmk-via-enabled-keychron-q6-pro-keyboard
