Crashes on Win 10 when changing lightning mode

[RedX2501]

I'm on windows 10 and have a 38gn950-b.

I installed HID, qt5 and the GUI opens fine.

I run it via powershell as admin with python gui.py Python version 3.9.2

I downloaded the code as as a zip today.

When I click pretty much any of the button it crashes with:

Traceback (most recent call last):
  File "F:\Drivers\27gn950controller-master\gui.py", line 61, in <lambda>

On the LG UltraGear ControlCenter the monitor is not recognized, I get the "Please connect USB cable (...) to PC and Monitor." I don't know why I'm getting that message since I have the mouse connected to the USB-Port of the monitor and it is working fine.

What can I do to help you fix this?

Was the LG UltraGear software running at that moment? It shouldn't. Maybe was in a background? That looks like somenthing was trying to access device at the same moment.

I looked today and there were no LG or UltraGear SW running (not event in the background) as far as I can tell.
