BTW, these are my current config for gpu setting

boot.initrd.kernelModules = [ "amdgpu" ];

  boot.kernelPackages = pkgs.linuxPackages_latest;
 
  boot.kernelParams = [
      "amdgpu.dc=1"
      "amdgpu.dcdebugmask=0x10"
  ];

  services.xserver.videoDrivers = ["amdgpu"];

  hardware.enableRedistributableFirmware = true;

  hardware.graphics.extraPackages = with pkgs; [
    amdvlk
  ];

  hardware.amdgpu.amdvlk.enable = true;
  hardware.amdgpu.opencl.enable = true;

And do you actually use OpenCL

I was advised to ask here instead of https://matrix.to/#/#users:nixos.org.

I installed home-manager flake on Pop!_OS 22.04 a few weeks ago and since then I got a few programs crashed when opening a home dir. I finally got to the bottom of this and renaming ~/.local/state/nix/profiles/profile to anything else fixes it. Or removing ~/.nix-profile/share from XDG_DATA_DIRS. Can someone explain why that happens and how can I fix this without launching all the problematic apps with env?
