GTK 4 App theming on hyprland does not work with nwg-look.

On hyprland I am using gsettings and nwg-look to change gtk-theme. For some reason gtk-4 apps are buggy with this, where using nwg-look it does change theme but after some time. And gsettings don't work at all. Changing the cursor theme using gsettings or nwg-look do not work either. But icon theme works with both. Firefox does change theme according to nwg-look but stuff like nautilus, clapper or gnome-calculator does not. I know nwg-look uses gsettings for settings themes but for me using gsettings from the terminal does not work at all for gtk-theme.

Hyprland Environment Variables:

env = XCURSOR_SIZE,24
#env = XCURSOR_THEME,BreezeX-RosePine
env = HYPRCURSOR_SIZE,12
env = HYPRCURSOR_THEME.BreezeX-RosePine-Linux

env = LIBVA_DRIVER_NAME,nvidia
env = __GLX_VENDOR_LIBRARY_NAME,nvidia

env = ELECTRON_OZONE_PLATFORM_HINT,auto

env = NVD_BACKEND,direct

env = XDG_CURRENT_DESKTOP,Hyprland
env = XDG_SESSION_TYPE,wayland
env = XDG_SESSION_DESKTOP,Hyprland

Zshrc:

export XDG_SESSION_TYPE="wayland"
export XDG_CURRENT_DESKTOP="Hyprland"
export WEBKIT_DISABLE_DMABUF_RENDERER=0

GTK-4 Settings.ini:

[Settings]
gtk-theme-name=Gruvbox-Dark
gtk-icon-theme-name=Colloid-Pastel-Yellow
gtk-font-name=SpaceMono Nerd Font Bold 11
gtk-cursor-theme-name=BreezeX-RosePine-Liux

The errors in xdg-desktop-portal status are recent and happened while I was troubleshooting. But my problem of gtk-4 themes not changing has been here for a while. It did used to work, my gtk-4 theme changed with nwg-look and gsettings but does not now.
