Hyprland / Qtile doesn't start correctly after upgrading to 24.05

Hi there,

In my NixOS configuration, I've a Variable to switch between Gnome, Qtile and Hyprland. I've updated my Flake from 23.11 to 24.05. After running the sudo nixos-rebuild switch --flake, home-manager switch --flake and sudo reboot Qtile and Hyprland doesn't start correctly (see Image), when I start Qtile/hyprland I only have a black screen. Gnome seems to works.

How can I fix this Issue?
