I don't really know if this is crashing the OS, but this was the only error that I could find. I have intel processor, plus Nvidia MX450 dedicated GPU. I am using hyprland on NixOS. My video and audio settings in hardware-configuration.nix are as follows :

# Graphics Stuff

  hardware.opengl = {
    enable = true;
    driSupport = true;
    driSupport32Bit = true;
  };

  hardware.nvidia = {
    modesetting.enable = true;
    open = true;
    nvidiaSettings = true; 
    package = config.boot.kernelPackages.nvidiaPackages.stable;
  };

  hardware.nvidia.prime = {
    offload = {
      enable = true;
      enableOffloadCmd = true;
    };
    intelBusId = "PCI:00:02:0";
    nvidiaBusId = "PCI:01:00:0";
  };

  # Audio Stuff

  services.pipewire = {
    enable = true;
    alsa.enable = true;
    audio.enable = true;
    alsa.support32Bit = true;
    pulse.enable = true;
  }; 

Hyprland parameters are as follows :

programs.hyprland = {
    enable = true; 
    xwayland = {
      enable = true;
    };
  };

x11 parameters :

services.xserver = {
    enable = true;
    layout = "us";
    videoDrivers = ["nvidia"];
    libinput = {
      enable = true;
    };
  };
