There are two issues:
Double vertical slabs from Double slabs mod dont lose their windowable tag

And the second, the scarier one is that vertical slabs from double slabs mod dont render once you place a window pane inside, and crash your game once you break them.

Also I wish there was some config file to fix issues like that, to add or remove blocks/mods for people that arent as savvy with datapacks as myself
