After recent updates my screen share has been broken for almost three weeks, I reinstalled xdg portals, made changes to the env variables and installed many missing dependencies and could get it to work 2-3 times but after a reboot it wasn't working again, it's stuck on an endless loop of building modifiers for the dma which I have no idea how I managed to get it to unstuck the times that it did work. I'm at a dead end and I might be missing something but how can it be when it used to work for 6-7 months before breaking?

From the logs I noticed that it takes an hour to start initializing stuff which is extremely weird...

after reconsidering some enivars and config files i've managed to fix it

I'm facing the same issue. Could you please share the changes you made to env vars that fixed it for you?
I've tried a sys upgrade, tweaking bitdepth in monitor.conf, but none worked.
journalctl keeps showing this

yeah i changed my envs to these ones
# Cursor Settings
env = XCURSOR_THEME,McMojave-cursors
env = XCURSOR_SIZE,24
# Desktop Environment Identification
env = XDG_SESSION_DESKTOP,Hyprland
env = XDG_CURRENT_DESKTOP,Hyprland
env = XDG_SESSION_TYPE,wayland
env = MOZ_ENABLE_WAYLAND,1
# NVIDIA GPU Configuration
env = WLR_RENDERER,gles2
env = WLR_NO_HARDWARE_CURSORS,1
env = GBM_BACKEND,nvidia-drm
env = __GLX_VENDOR_LIBRARY_NAME,nvidia
env = LIBVA_DRIVER_NAME,nvidia
# Toolkit Backends
env = QT_QPA_PLATFORM,wayland
env = SDL_VIDEODRIVER,wayland
env = ELECTRON_OZONE_PLATFORM_HINT,auto
# UI Styling and Themes
env = GTK_THEME,wildberries

env = QT_QPA_PLATFORMTHEME,qt6ct
env = QT_STYLE_OVERRIDE,Adwaita-dark
env = QT_WAYLAND_DISABLE_WINDOWDECORATION,1
env = QT_AUTO_SCREEN_SCALE_FACTOR,1
and i added a pipewire config to ~/.config/pipewire/pipewire.conf.d/no-modifiers.conf
context.properties = {
support.dmabuf = true
support.dmabuf.modifiers = false
}

Thanks, lordworm1996.
I figured out which env var was the culprit in my case (for anyone stumbling across this thread in the future):
env = __NV_PRIME_RENDER_OFFLOAD,1I'd earlier set a lot of Nvidia env vars to force Hyprland to use Nvidia GPU, but after going through the recommended approach again mentioned in hyprland's wiki for multi-gpu, I ended up removing most of these env vars.
