Rant about Plasma login manager and Kde wayland problems on cachyos and nvidia

I don't know if this has happened to you guys but I hate the fact that the plasma login manager doesn't work with other desktop environments other than gnome and Niri. All of them show a black screen on login and even fucking hyprland despite being on wayland has breeze cursor artifact remain making it two cursors on my desktop. I can't even use lightdm because my kde plasma won't boot at all!! I have to switch to gnome or niri for sometime before I can logout and enter plasma normally like why?? When is kde going to fix this issue with other login managers?? Or is it a cachyos or nvidia problem??
