My problems seemed to be related to Overbridge again. Where last time I simply fixed it by disconnecting and re-connecting things (trying out different ports too), this time I somehow couldn’t get it to work again.
But then I tried connecting my devices directly to my laptop without Overhub and that worked.
I was using a cable I bought myself to go from usb-c (laptop) to usb 3 micro male b (overhub) and maybe that cable is not the best quality.
I then tried connecting Overhub via the original usb a male cable via a usb a -> usb c adapter cable and that worked.
Strangely after that I tried Overhub again with the other cable and it worked as well. I have reconnected and powered off/on things many times before, so I have no idea why it is working now again. The connection of the cable seems to be stable even when I wiggle it around.
So yeah, I guess what I’ve learned from this is that you better first try swapping different cables / adapters before reinstalling Overbridge many times over. It’s a lot quicker
