Screen turns blank on Nixos
The app opens, 3 seconds it work and all the buttons respond, then it suddenly turns white blank and I can't refresh. I am on the latest Nix Os version and I just installed today. Reboot didn't work. 


nixos-unstable.heroic in your config.nix topackageOverrides solution will work if you just change electron_27 to electron_23.nixpkgs-unstable if you decide you want to stick with Heroic.pkgs.heroic-unwrapped.overridenixos-unstableheroicconfig.nixpackageOverrideselectron_27electron_23nixpkgs-unstableerror: undefined variable 'heroic-unwrapped'
