Surface Pro 8 Fails to Build Displaylink

[NegligentBiochemist]

Using the following import code, Displaylink now fails to build on my Surface Pro 8, since a few days ago. I've tried commenting out the surface-pro-intel bit, and it builds properly, so I'm guessing it's a problem with this.

imports =
    [ # Include the results of the hardware scan.
      (import "${home-manager}/nixos")
     "${builtins.fetchGit { url = "https://github.com/NixOS/nixos-hardware.git"; }}/microsoft/surface/surface-pro-intel"
      ./hardware-configuration.nix
    ];

#nix-prefetch-url --name displaylink-580.zip https://www.synaptics.com/products/displaylink-graphics/downloads/ubuntu-6.0?filetype=exe
  services.xserver.videoDrivers = [ "displaylink" "modesetting" ];

The logs are long enough that the nixos-rebuild gets hidden from me, and I can't figure out how to save the full logs to a file, but this is the bit I think is most important (purely because it's the only bit highlighted in red).
