Entity Spawn Procedure makes my game infinitely start up

I made this procedure https://imgur.com/a/Lc3udOa, it works fine when the first villager spawns on a world. But as soon as I leave the world and join again the map is just infinitely loading and im stuck in the void, then if i close the game, and try starting up and joining, the world just doesnt load at all. If i load a new world where a villager never spawns it runs just fine. Any help?
