UHK 60v2 Requires Re-plugging After Mac Wakes from Sleep

[Recordedfieber]

Description

When my MacBook goes to sleep and wakes up, the UHK 60v2 keyboard partially wakes (lock screen appears), but the backlighting and LEDs stay off, and the keyboard becomes unresponsive. I need to unplug and re-plug the USB cable for it to work again.

Steps to Reproduce

Connect UHK 60v2 to a MacBook (directly or via a hub).
Allow the Mac to sleep or turn off the display.
Press a key to wake the Mac.
Observe the keyboard behavior: no backlighting, LEDs, or responsiveness.

Environment

UHK Model: UHK 60v2
Firmware:
Right keyboard half firmware: UltimateHackingKeyboard/firmware: 12.2.0
Left keyboard half firmware: UltimateHackingKeyboard/firmware: 12.2.0
OS: macOS
Connection: Direct or via USB hub

Additional Notes

Similar issue reported when connected to a monitor's USB hub.
Possibly started after firmware update although the problem was persistent throughout the previous fw versions (12.0.0)

Impact

Not critical but inconvenient. Affects workflow by requiring re-plugging.

I see something similar with the UHK80.
When I put my computer to sleep the keyboard still says connected.
When I press a key the computer does not wake up.
I tested this on a Dell laptop with Linux and an HP laptop with Windows, the behavior is the same.
I started on 12.2.0 (the FW my UHK80 came with) and I have not seen this, it behaved like it supposed to behave.
After I upgraded to 12.3.0 I started seeing this behavior where it seems the keyboard is not aware anymore that the computer it is connected to went to sleep.
Should I open a separate issue for this?

The keyboard is connected via USB and the two halves are connected via the spiral cable.
