Movink 13 Pen not working at all

Hey, I just got a Movink 13 and have problems setting it up. The display works fine but I cannot get any pen input to windows at all.

I have tried deleting and redownloading the Wacom drivers but that didn‘t work. My motherboard has 2 USB 4 ports in the back, both of which have the same issue.

But here‘s the thing, the pen does work inside of the OSD menu of the Movink itself. And also: when I plug it into the front USB-C port of my PC the screen obviously doesn‘t turn on since it‘s not USB4 *but* the pen actually works!

So now I‘m thinking that Wacom maybe sent me a faulty cable that can‘t handle the data load of everything at once?

Does anyone have any ideas on what I could try to fix this? Feels like I tried everything
