I've had the same issue. Nix uses KDE Plasma by default, which uses a compositor that struggles with some video drivers.

Fortunately, installing from command line is practically the same, especially if you do your partitioning beforehand.

That's a more unique problem. I'm not sure what to do about it either. Did /dev/nvme0n1 just never populate? My best guess is that you booted emulated BIOS instead of UEFI.
