Black screen on UWSM stop (didn't do it a week ago or something)

[PoutineSyropErable]

When uwsm managed, doing hyprctl dispatch exit, or uwsm stop cause a black screen.
This happens because hyprland crash and core dump.

I started seeing this issue yesterday. Idk if i should post this on uwsm.

the uwsm related segment:

exec-once = uwsm app -- hyprpaper
exec-once = uwsm app -- hypridle
exec-once = uwsm app -- nm-applet
exec-once = uwsm app -- kanata
exec-once = uwsm app -- /usr/lib/polkit-kde-authentication-agent-1


exec-once = uwsm finalize
####### UWSM Managed END ###########

# since i have manual toggling for it
exec-once = ironbar
exec-once = "$HOME/.config/waybar/waybar_toggle.sh"

~/.config/uwsm/env

export XDG_SESSION_TYPE=wayland
export XDG_CURRENT_DESKTOP=Hyprland

export HYPRSHOT_DIR="$HOME/Pictures/Screenshots"
