The messages here are mostly in German, but I'll try to translate mist of it:

I really hope someone can help me out here..
EDIT: I kinda forgot to actually mention my problem. When booting nornall, I get stuck at a lonely white blinking cursor on a black screen, so startx seems to make some problems. I enter a TTY and run startx and this is what I get when running startx:
SOLUTION
- Uninstall your current nvidia driver (for example using sudo apt remove nvidia-driver on Debian)
- Install the headers for your kernel. your kernel you can check rather easily by running neofetch
- Install the headers required for your kernel. Do that by listing all packages with your kernel name in it. For example like this:
apt list *6.9.7+bpo* - reboot, install your nvidia driver again and rovoot again. Should be done.
It appears that you're trying to install a kernel for which dkms can't build the version of the v4l2loopback kernel module that you have.
I don't see why this would affect Gnome, but if it's causing problems for the rest of the system maybe try uninstalling v4l2loopback-dkms until you can get a version that works, or else use an older kernel.
Alternately, if you're feeling brave and this is the same version that's in debian stable right now, you could edit /usr/src/v4l2loopback-0.12.7/v4l2loopback.c and replace strlcpy with strscpy in two places.
