I’m on the same Hyprland version (and ml4w dotfiles) and fixed this with a manual install. Clone the repo into ~/.config/hypr/plugins, run make all, load it with hyprctl plugin load ~/.config/hypr/plugins/Hyprspace/Hyprspace.so, confirm with hyprctl plugins list, then add to ~/.config/hypr/conf/custom.conf this line bind = $mainMod, L, exec, hyprctl dispatch overview:toggle and finally try SUPER + L to start.

Works fine for me.
